METHOD FOR PRODUCTION OF 2-AMINO-5-CHLOROBENZHYDROL, 2-N-METHYLAMINO-5-CHLORBENZHYDROL AND M-CHLOROBENZHYDROL Russian patent published in 1996 - IPC

Abstract RU 2065435 C1

FIELD: organic synthesis. SUBSTANCE: 2-amino-5-chlorobenzophenone, 2-N-methylamino-5-chlorobenzophenone and m-chlorobenzophenone (as derivatives of chlor-substituted benzophenone) are suspended in lower alcohol. The process is followed by reduction with the help of sodium boron hydride at 30-70 C. Molar ratio of said derivative of sodium boron hydride is 0.02: 0.06-0.01. Thus obtained reaction mixture is treated by 0.1-1.0 N hydrochloric acid or by 3-15 % aqueous solution of acetic acid followed by isolation of desired product. EFFECT: improves efficiency of the method. 4 tbl
