Abstract
Process for the preparation of 2-phenyl-imino-3-phenyl-4-alkyl-4-thiazolines of the general formula ** (See formula) ** and its salts and mixtures of these compounds, where one of the radicals R is by the group Py- (CH = OH) n, where Py means a pyridyl radical and n 0, 1 or 2, and the other by a group N, N-dialkylamino-alkoxy or an alkoxy group, whose alkyl group contains 4-5 carbon atoms, and R1 by an alkyl group with 1-5 carbon atoms, characterized in that a 1,3-diphenyl-thiourea of the general formula ** (See formula) ** where the radicals R have the meaning indicated above, or a salt thereof is reacted with a halogenomethyl-alkyl-ketone where the alkyl group contains 1-5 carbon atoms and, if desired, the salts obtained are transformed into the bases Free or a free base in their salts and the obtained mixtures are separated into their components.
