Reaction Conditions

Reaction Steps

A mixture of 3-methyl-but-2-enoic acid 1-methylsulfanyl-1-pyrrolidin-1-yl-meth-(Z)-ylideneamide (130 mg, 0.575 mmol) and phenyl hydrazine (0.6 ml, 5.75 mmol) was stirred for 3 hours at 100° C. The mixture was cooled, diluted with ethyl acetate and washed twice with water. The organic layer was separated, dried over sodium sulfate, filtered and concentrated. The crude material was purified by silica gel column chromatography using 50% ethyl acetate in hexane affording 5-(2-methyl-propenyl)-1-phenyl-3-pyrrolidin-1-yl-1H-[1,2,4]triazole (60 mg, 38.87%) as colorless liquid. MS: m/z=268.8 (M+H+)
