Acetyl chloride → 2-Acetylamino-4,5,7,8-tetrahydro-thiazolo(4,5-d)azepine-6-carboxylic acid tert-butyl ester

Participants

Reaction Steps

95 mg acetyl chloride was added to 312 mg 2-amino-4,5,7,8-tetrahydro-thiazolo[4,5-d]azepine-6-carboxylic acid tert-butyl ester in 5 mL pyridine at 15° C. The reaction was stirred 3 h at RT. The reaction was diluted with dichlormethane and 1 mL water was added. The solution was filtered over 40 mL Alox and 100 mL Extrelut and evaporated to give 127 mg of the desired product. (M+H)+: 312
