Chemistry, isomerism

Tioconazole is a chiral drug and contains a stereocenter . So there are two stereoisomers , the ( R ) form and the ( S ) form. The commercial preparations contain the drug as a racemate [1: 1 mixture of the ( R ) and ( S ) isomers]. For synthesis, 1- (2,4-dichlorophenyl) -2- (1 H -imidazol-1-yl) -ethanol (an intermediate product of the miconazole synthesis) is deprotonated with sodium hydride and then with 2-chloro-3- (chloromethyl) -thiophene implemented.
