Participants

Reaction Steps

3-Amino-4,4,4-trifluoro-2-methyl-but-2-enoic acid ethyl ester (25.5 g, 124 mmol) was cooled to 0° C. and methyl hydrazine (7 ml, 132 mmol) was added dropwise. The mixture was allowed to warm to room temperature and heated to 50° C. for 20 hours. The mixture was allowed to cool to room temperature and was stirred for 16 hours. The mixture was cooled to 0° C. and saturated aqueous sodium hydrogencarbonate solution (50 ml) was added. The solid was removed by filtration and washed with cold water (0° C.) to give the product as a white solid (8.46 g, 38% yield over two steps).
