PyBroP (212 mg, 0.45 mmol) and 1-cyclopropylmethyl-piperidine-4-carboxylic acid from Example E15a (76 mg, 0.42 mmol) were added to a solution of 4-aminomethyl-N-(4-chloro-phenyl)-3,N-dimethyl-benzamide from Example E115.2 (100 mg, 0.35 mmol) in dichloromethane (5 ml) and DMF (1 ml). The mixture was stirred at room temperature for 18 h then solvents were removed in vacuo and azeotroped with toluene. The residue was purified by preparative HPLC (eluant; 0.5% 35% ammonia:9.5% methanol:90% dichloromethane) to give a white powder identified as the title compound (34 mg, 22%).
