Procedure
NH4Cl (0.150 g, 2.8 mmol) is added to a solution of 1-methyl-1H-imidazole-2-carboxylic acid ethyl ester (15.5 g, 101 mmol) in ammonium hydroxide 35% (112 mL) and the reaction is stirred for 6 h at 100° C. in a sealed reaction flask. The reaction is cooled to 0° C. and the solid formed filtered and washed with ice water and ether to give 1-methyl-1H-imidazole-2-carboxylic acid amide as brown crystals (6.9 g, 55%).
