Procedure

(2S,4R)-3-(4-{Acetyl-[1-(4-methoxy-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-amino}-phenyl)-propionamide was prepared from (2S,4R)-3-(4-{Acetyl-[1-(4-methoxy-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-amino}-phenyl)-propionic acid. To a solution of 3-(4-{acetyl-[1-(4-methoxy-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-amino}-phenyl)-propionic acid (21 mg, 0.042 mmol) in dimethylformamide (200 μl) was added HATU (24 mg, 0.063 mmol), HOBt (8.5 mg, 0.063 mmol), NH4Cl (4.5 mg, 0.084 mmol) and DIPEA (29 μl, 0.168 mmol). Upon consumption of the starting unit (2.5 hours), the mixture was diluted with EtOAc (10 ml) and washed with sat. NaHCO3 (4×10 ml). The EtOAc layer was collected, dried over Na2SO4, filtered, and concentrated to afford the title compound (17.2 mg, 82%).
