236 mg (1.1 mmol) of 1-(thiophen-2-yl)-1,2,3,4-tetrahydroisoquinoline, 380 mg (1.0 mmol) of HATU and 263 μl (1.9 mmol) of NEt3 were added in succession to a solution of 275 mg (1.0 mmol) of 4-oxo-4-(3-(trifluoromethyl)benzylamino)butyric acid (intermediate VVV01) in THF (8 ml) and the mixture was then stirred for 24 h at RT. Then it was diluted with EE (30 ml) and washed twice with a 4M aqueous NH4Cl solution and with a 1M aqueous NaHCO3 solution. The organic phase was dried over MgSO4, filtered and concentrated to small volume under vacuum. Column chromatography (EE) of the residue produced 410 mg (0.87 mmol, 87%) of 4-oxo-4-(1-thien-2-yl-3,4-dihydroisoquinolin-2(1H)-yl)-N-(3-(trifluoromethyl)benzyl)butyric acid amide. MS: m/z 473.1 [M+H]+.
