実験手順

A solution of 3-(4-aminophenyl)-5-{[(2-oxopyrrolidin-1-yl)carbonyl]amino}isothiazole-4-carboxamide (9.6 g, 0.027 mol), diisopropylethylamine (5.3 g, 0.046 mol) in dimethylformamide (150 mL) at ambient temperature was treated with para-Tolyl isocyanate (4.0 g 0.03 mol) over 20 minute period. The resulting mixture was stirred at ambient temperature for 2 hr. The reaction mixture was concentrated in vacuo to give an off white solid, which was stirred in EtOAc (150 mL), filtered the solid and washed with EtOAc to give the title compound as a white solid (11.8 g, 88%).
