反応手順

To a mixture of 5-amino-2-(naphthalen-2-ylamino)thiazole-4-carboxamide (0.2 g, 0.70 mmol) in pyridine (5 mL) was added a solution of 4-methyl-3-nitrobenzoyl chloride in pyridine (3 mL) at 0° C. under nitrogen atmosphere. The mixture was allowed to warm up to rt, and stirred for 16 hrs at rt. The solvent was evaporated, and the crude residue was suspended into EtOAc (20 mL). The resulting solids were collected by filtration and washed with MeOH (2×5 mL) to give 0.21 g (66% yield) of the titled compound.
