Procedure

To a mixture of 6-(2-cyanophenyl)-2-(3-fluorophenethylamino)nicotinic acid (110 mg, 0.30 mmol), (R)-tert-butyl 3-(2-(aminomethyl)-5-oxopyrrolidin-1-yl)propylcarbamate (125 mg, 0.46 mmol), HOBT (107 mg, 0.46 mmol), and HBTU (174 mg, 0.46 mg) in RB flask was added DMF and the mixture was stirred at r.t. for 1 h. LC/MS indicated the reaction was complete and the mixture was filtered and purified on RP-HPLC using a mixture of acetonitrile and water to give (R)-tert-butyl 3-(2-((6-(2-cyanophenyl)-2-(3-fluorophenethylamino)nicotinamido)methyl)-5-oxopyrrolidin-1-yl)propylcarbamate (72 mg, 39%). LRMS (M+H+) m/z 615.2.
