Reaction Steps

To a suspension of 3-amino-3,4-dihydro-1H-quinolin-2-one (177.6 mg, 0.59 mmol) (prepared according to the procedures by Davis, A. L.; et al, Arch. Biochem. Biophys., 102, 48 (1963)) in CH3CN (5 mL) was added DIPEA (0.24 mL, 1.44 mmol), followed by addition of benzene sulfonylchloride (0.09 mL, 0.71 mmol). The mixture was stirred at RT for 1.5 h, then concentrated in vacuo. The residue was taken into EtOAc (30 mL), washed with water, brine, dried (MgSO4) and concentrated. The residue was chromatographed (silica gel) eluting with EtOAc (50-90%) in hexane to give the title compound (140 mg, 78%).
