Embodiment 1

[0035] Example 1: Preparation of 1-[4-(dimethylamino)butyl]-5-benzyloxy-2-(4-benzyloxyphenyl)-3-methyl-1H-indole

[0036] Step A): Preparation of 4-nitrobenzyloxybenzene

[0037] Put 4-nitrophenol (20.0g, 0.152mol) and anhydrous potassium carbonate (131.1g, 0.950mol) in a 1000mL flask, use acetone as solvent, add dropwise benzyl chloride (12.0g, 0.095mol), and reflux reaction After 24 hours, the solvent was evaporated under reduced pressure, the residue was stirred with water, filtered with suction, and dried to obtain 19.8 g of a light yellow solid with a yield of 90.8%. m.p.105-106°C. ESI-MS: m / z139 ([M+H] + ).

[0038] Step B): Preparation of 4-benzyloxyaniline

Abstract

The invention belongs to the technical field of medicines, and relates to a phenylindole derivative and application thereof.The phenylindole derivative comprises stereisomer and pharmaceutically-applicable salt of a phenylindole compound and has the structural formula (please see the formula in the description).The phenylindole derivative and the acid-added pharmaceutically-applicable salt of the phenylindole compound can be used in cooperation with existing medicines or used independently as an estrogen receptor regulator for treating or preventing various diseases related to estrogen functions such as bone loss, fractures, bone rarefaction, hectic fever, LDL cholesterol level rise, cardiovascular diseases, cognitive deficits, brain degeneration diseases, anxiety, depression caused by estrogen deficiency, sexual dysfunction, hypertension, retinal degeneration, cancers and especially osteoporosis.

Description

technical field [0001] The present invention relates to phenylindole compound and its preparation method, and its application in the preparation of estrogen receptor regulator medicine. Background technique [0002] Compounds that mimic estrogen-like effects have a wide range of therapeutic and prophylactic applications, including: treatment of osteoporosis, relief of menopausal symptoms, treatment of acne, treatment of dysmenorrhea and dysfunctional uterine bleeding, prostate cancer and prevention of cardiovascular disease. [0003] Studies have found that there are two types of estrogen receptors (ER): ERα and ERβ. After the ligand binds to these two isoforms, it exerts physiological effects with different tissue specificities. [0004] What is needed in the art is a compound that can produce a positive response like estrogen replacement therapy but without adverse side effects or with reduced side effects, and exert tissue-specific estrogen-like effects on the body.
