Embodiment 1

[0143] Embodiment 1 prepares compound 1 provided by the invention

[0144] The preparation process is as follows:

[0145]

[0146] Accurately weigh 3.0g of about 24.6mmol of 3-hydroxybenzaldehyde, dissolve it in 100mL of acetone, stir to dissolve, add 6.8g, equivalent to 50mmol of K 2 CO 3 Solid powder, stirred vigorously, and then slowly added dropwise 2.75g (25.6mmol) of N,N-dimethylformyl chloride, a small amount of bubbles were generated. After the reaction is stable, move the reactor into a 60°C oil bath and heat to reflux, TLC detection, stop the reaction after 21h, cool, filter, discard the filter residue, evaporate the filtrate to dryness and add saturated NaHCO 3 The solution was diluted, left to stand and separated and extracted with ethyl acetate, the organic extract was collected, washed with water, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to obtain an oily substance, which was purified by silica gel column chroma...

Abstract

Disclosed in this invention are compounds and the uses as L-type calcium channel blocker and / or acetylcholinesterase inhibitor thereof. The uses of said compounds in the manufactures of a medicament for the treatment of cardiovascular diseases, apoplexy or senile dementia are also disclosed in the present invention.

Description

technical field [0001] The invention relates to the field of chemical synthesis, in particular to a compound and its application as an L-type calcium channel blocker or / and an acetylcholinesterase inhibitor. Background technique [0002] Alzheimer's disease is a degenerative disease of the central nervous system characterized by chronic, progressive cognitive impairment and memory impairment. The main pathological features are senile plaques, neurofibrillary tangles and neuron loss, which seriously affects patients. Cognition, memory, language function and personal life ability and emotional personality. At present, the more accepted pathology of Alzheimer's disease in the world is the "cholinergic deficiency theory". The theory is that the loss of the neurotransmitter choline acetate in the patient's brain is the key cause of Alzheimer's disease. [0003] Cholinesterase is a key enzyme in biological nerve transmission. In cholinergic synapses, this enzyme can degrade acet...
