Popis: | 1. Reaction of 2-bromoethyldiazoacetate with free secondary amines or primary amine chlorohydrates in the presence of anhydrous K2CO3 in acetonitrile at 20°C affords the correponding aminoethyldiazoacetates in a yield of up to 80%. 2. Reaction of 2-bromoethyldiazoacetate with free primary amines in the presence of K2CO3 is accompanied by ammonolysis of the diazoester and affords previously unknown N-alkyl-N-(2-hydroxyethyl)diazoacetamides in yields of up to 70%. |
