Embodiment 1

[0108] Example 1: Synthesis of 3-(chroman-6-ylmethyl)-1-(4-fluoro-benzyl)-1-(1-methyl-piperidin-4-yl)-urea (compound# 45), ER10058

[0109]

[0110] A solution of triphosgene (148 mg, 0.500 mmol) in DCM (5.0 mL) was slowly added to chroman-6-yl-methylamine mono-hydrochloric acid (99 mg, 0.500 mmol) and triethylamine (50 mg, 0.500 mmol) at 0 °C ) in DCM (5.0 mL). The mixture was stirred at room temperature for 1 hour. Ice water (20 mL) was added, and the mixture was extracted with DCM (20 mL×2). The organic phase was washed with brine, washed with Na 2 SO 4 Drying, filtration and concentration under vacuum gave the product (45-1) as an oil (80 mg, 85% yield).

[0111]

[0112] To a solution of 1-methyl-piperidin-4-ylamine (19 g, 88 mmol) in 500.0 mL of dichloromethane at room temperature was added 4-fluorobenzaldehyde (11 g, 90 mmol), followed by the slow addition of triacetoxy Sodium borohydride (33g, 180mmol), and 10ml acetic acid. The mixture was stirred overnig...

Embodiment 2

[0115] Embodiment 2: Synthesis of 3-(chroman-6-ylmethyl)-1-(4-fluorobenzyl)-1-((1-methylazetidin-3-yl) methyl)urea ( H001-064)ER10191

[0116]

[0117] 3-(chroman-6-ylmethyl)-1-(4-fluorobenzyl)-1-((1-methylazetidin-3-yl)methyl)urea (H001-064) ER10191 The synthesis method was similar to compound #45: using chromane-6-methylisocyanate (45-1) (0.25 mmol) gave white solid H001-064 (12 mg, 12% yield). LCMS: [M+1] + 398.3.

Embodiment 3

[0118] Example 3: Synthesis of (S)-3-(chroman-6-ylmethyl)-1-(4-fluorobenzyl)-1-((1-methylpyrrolidin-2-yl)methyl ) urea (H001-065) ER10192

[0119]

[0120] (S)-3-(chroman-6-ylmethyl)-1-(4-fluorobenzyl)-1-((1-methylpyrrolidin-2-yl)methyl)urea (H001- 065)ER10192

[0121]The synthesis method was similar to compound #45: using chromane-6-methylisocyanate (45-1) (0.5 mmol) gave white solid H001-065 (70 mg, 34% yield). LCMS: [M+1] + 412.3.

Abstract

The invention provides a compound with a central nervous system disease treatment effect and a structure shown represented by formula I. The compound has 5-HT2A receptor antagonist or inverse agonist activity, and has the advantages of high selectivity to 5-HT2A receptors, low cardiotoxicity, good metabolic stability, and no toxic or side effect. The compound can be used for treating certain mental diseases (such as depression, anxiety, psychosis, schizophrenia, insomnia and autism) and mental disorder symptoms related to or concurrent with central nervous system degenerative diseases (such as Alzheimer's disease, Parkinson's disease, Huntington's disease and Lewy small body dementia).

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a 5-HT2A receptor antagonist or inverse agonist with therapeutic effect on central nervous system diseases and application thereof. Said compound can be used for the treatment of certain mental illnesses (such as depression, anxiety, psychosis, schizophrenia, insomnia, autism, etc.) and degenerative diseases of the central nervous system (such as Alzheimer's disease, Parkinson's disease, Huntington's disease, dementia with Lewy bodies, etc.) related or concurrent mental disorder symptoms. Background technique [0002] Serotonin or 5-hydroxytryptamine (5-HT) plays an extremely important role in the physiological functions of the human body. In the central nervous system, 5-HT is an important neurotransmitter and neuromodulator, which regulates various behaviors such as sleep, diet, activity, learning and memory, body temperature, blood pressure and pathological states (such as anx...
