Reaction Steps

75 mg (0.3 mmol) of 4-[(tert-butoxycarbonyl)amino]tetrahydro-2H-pyran-4-carboxylic acid together with 110 mg (0.3 mmol) of HATU and 47 mg (0.4 mmol) of 4-dimethylaminopyridine were initially charged in 2 ml of DMF, and 60 mg (0.2 mmol) of N-[5-(3,4-dimethylphenyl)piperidin-3-yl]benzamide were added. The reaction mixture was stirred overnight at RT and then purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 46 mg (44% of theory)
