Abstract

Imidazoles from Alclimines and Imidoyl Chlorides J. Org. Chem., Vol. 42, No. 7, 1977 1153 pure 6a, followed by a mixture of 6a and 8a, then pure 8a, then a mixture of Sa and 7a, and finally pure 7a. The compounds were recrystallized from ether, high-boiling ligroin, or ligroin- chloroform mixtures. Alcohol 7a and tosylate 7b gave mp 101-102 and 150-151" C, respectively; alcohol 8a and tosylate 8b gave mp 102-103 and 180-181 OC, respectively.
