Participants

Reaction Steps

Into a solution of tert-butyl (3R)-3-[[5-(1,3-benzothiazol-2-yl)-6-oxo-2-(piperidin-4-yl)-1,6-dihydropyrimidin-4-yl]amino]piperidine-1-carboxylate (100 mg, 0.20 mmol, 1.00 equiv) and triethylamine (29.7 mg, 0.29 mmol, 1.50 equiv) in dichloromethane (5 ml) was added methyl chloroformate (14.8 mg, 0.16 mmol, 0.80 equiv). The resulting mixture was stirred for 2 h at room temperature. Concentration under reducing pressure gave 100 mg of the title compound as a crude product, which was used directly for next step without further purification. MS m/z [M+H]+ (ESI): 569.
