Procedure

To a solution of (S)-2-amino-N-(1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)thiazole-5-carboxamide (2) (100 mg, 0.24 mmol) and triethylamine (0.07 mL, 0.48 mmol) in anhydrous THF (5 mL), acetyl chloride (0.025 mL, 0.35 mmol) and 4-(dimethylamino)pyridine (2.5 mg, 0.02 mmol) were added and the resulting mixture was stirred at RT for 4 h. The mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by ISCO column chromatography (silica gel cartridge, 0-10% MeOH-DCM) to afford the product, (S)-2-acetamido-N-(1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)thiazole-5-carboxamide (compound 50). ESI-MS m/z: 467.0 [M+H]+.
