Participants

Reaction Steps

1 g of ethyl 2-(2-amino-4-thiazolyl)-2-[(Z)-(2-bromoethoxy)imino]-acetate in 20 ml of dimethylformamide is warmed to 50° C. for 12 hours with 9.5 g of sodium azide. The mixture is diluted with ethyl acetate, washed three times with water, dried over magnesium sulphate and evaporated. After recrystallization from acetone/isopropanol, there is obtained 0.85 g of ethyl 2-(2-amino-4-thiazolyl)-2-[(Z)-(2-azidoethoxy)imino]-acetate of melting point 123°-124° C.
