Reaction Steps

To a mixture of 6-(2-cyanophenyl)-2-(3-fluorophenethylamino)nicotinic acid (510 mg, 1.41 mmol), (R)-tert-butyl 2-(aminomethyl)pyrrolidine-1-carboxylate (424 mg, 2.11 mmol), HOBT (285 mg, 2.11 mmol), and HBTU (800 mg, 2.11 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 2-((6-(2-cyanophenyl)-2-(3-fluorophenethylamino)nicotinamido)methyl)pyrrolidine-1-carboxylate (695.1 mg, 91%). LRMS (M+H+) m/z 544.2.
