Abstract

The invention comprises aminocarbinols of the formula <FORM:0683950/IV (b)/1> and amino-alkenes of the formula <FORM:0683950/IV (b)/2> and their salts, except when made by the process of Specification 682,160; n is 3-8, R1 and R2 are the same or different alkyl groups of 1-4 carbon atoms or else complete a morpholine, pyrrolidine, piperidine or N-methylpiperazine ring. The compounds are made in each case by reacting the corresponding chlorine or bromine compounds with HNR1R2, preferably using two mols. of the latter. Examples describe the preparation of the following: 4-piperidino-1 : 1-diphenylbutanol, 5 - morpholino - 1 : 1 - diphenylpentanol, 5 - dibutylamino - 1 : 1 - diphenylpentanol, 5 - pyrrolidino - 1 : 1 - diphenyl - pentanol, 6 - piperidino - 1 : 1 - diphenylhexanol, 6 - pyrrolidino - 1 : 1 - diphenylhexanol, 6 - morpholino - 1 : 1 - diphenylhexanol, 6 - dimethylamino - 1 : 1 - diphenylhexanol, 6 - diethylamino - 1 : 1 - diphenylhexanol, 6 - dibutylamino - 1 : 1 - diphenylhexanol, 6-(41-methylpiperazino)-1 : 1-diphenylhexanol, 9-piperidino-1 : 1-diphenylnonanol, 4-diethylamino - 1 : 1 - diphenylbutene, 5 - morpholino - 1 : 1 - diphenylpentene, 5 - pyrrolidino-1 : 1 - diphenylpentene, 6 - piperidino - 1 : 1 - diphenylhexene, 6 - dimethylamino - 1 : 1 - diphenylhexene, 6-(41-methylpiperazino)-1 : 1-diphenylhexene, 9 - piperidino - 1 : 1 - diphenylnonene, 9 - dibutylamino - 1 : 1 - diphenylnonene, 9 - morpholino - 1 : 1 - diphenylnonene and 9 - pyrrolidino - 1 : 1 - diphenylnonene. Salts described are hydrochlorides and oxalates. A further method of preparing the aminocarbinols is described in Specification 682,161. The starting materials are made by reacting chloro- or bromo-esters Hal-(CH2)nCOOR with a phenylmagnesium halide or phenyllithium to give (C6H5)2C(OH)-(CH2)n-Hal, and if desired dehydrating the latter to the alkenes (C6H5)2C : CH(CH2)n-1-Hal by distillation alone or with a mineral acid. Examples are given of the preparation of the following: 4 - chloro - 1 : 1 - diphenylbutanol, 5 - bromo - 1 : 1 - diphenylpentanol, 6 - bromo - 1 : 1 -diphenylhexanol, 9 - bromo - 1 : 1 - diphenylnonanol, 4 - chloro - 1 : 1 - diphenylbutene, 5 - bromo - 1 : 1 - diphenylpentene, 6 - bromo - 1 : 1-diphenylhexene and 9-bromo-1 : 1-diphenylnonene. According to the Provisional Specification n may be up to 11, the phenyl groups may be substituted and if NR3R4 is a heterocyclic ring it may carry alkyl substituents. It is also stated that the halocarbinols may be dehydrated by heating with carboxylic acid chlorides or anhydrides.
