Embodiment 1

[0027] Example 1 Preparation of 1-(4-nitrophenyl)-3-phenyl-3-(4-chloroanilino)-1-acetone oxime

[0028]

[0029] Add 1.06 g (0.01 mol) of benzaldehyde, 1.28 g (0.01 mol) of 4-chloroaniline and 18 ml of absolute ethanol in the reaction flask, stir at room temperature for 10 minutes, then add 1.65 g (0.01 mol) of 4-nitroacetophenone And catalytic amount of concentrated hydrochloric acid, stirred at room temperature; the precipitated solid was filtered by suction and washed with absolute ethanol. The obtained solid was suspended in 20ml ethanol and washed with saturated NaHCO 3 The aqueous solution was neutralized to alkaline, filtered with suction, and the filter cake was washed with a small amount of absolute ethanol. The crude product was recrystallized in a mixed solvent of ethanol / water (volume ratio 1:1) to obtain 3.43 g of a light yellow powder solid, with a yield of 83%.

[0030] 1.9 grams (5 mmol) of the above-mentioned solid and 20 ml of ethanol were added to the re...

Abstract

The invention relates to a non-steroidal androgen receptor modulator compound containing 1, 3-diaryl-3-aromatic amine-1-acetoxime compound (I), or relative medical acceptable salt and a relative preparation method. The invention also relates to a drug compound of 1, 3-diaryl-3-aromatic amine-1-acetoxime compound (I) and relative medical acceptable salt. The1, 3-diaryl-3-aromatic amine-1-acetoxime compound (I) or relative medical acceptable salt has androgen receptor antagonistic activity, therefore, the compound can be used to prepare the non-steroidal drug for preventing or/treating prostatic hyperplasia, prostate cancer, hirsutism, serious androgen dependence alopecia and acne or the like.
