Na. Nedolya et al., DIRECTED SYNTHESIS OF ISOMERIC THIAZOLE AND IMIDAZOLE DERIVATIVES FROM METHYL ISOTHIOCYANATE, Tetrahedron letters, 38(35), 1997, pp. 6279-6280
Reaction of methyl isothiocyanate with two equivalents of lithium diis
opropylamide, followed by alkylation with dimethyl sulfate gives 2-met
hyl-5-N, N-dimethylaminothiazole in a high yield. The isomer, 1-methyl
-2,5-bis(methylthio)imidazole is obtained in a high yield, if prior to
methylation, the reaction mixture is stirred for some period with wat
er at room temperature. (C) 1997 Elsevier Science Ltd.
