A mixture of the title compound from Example A(1) ((4-amino-2-phenylamino-thiazol-5-yl)-(3-nitrophenyl)-methanone, 520 mg, 1.53 mmol) and 10% palladium on carbon (80 mg) in THF (10 mL) was stirred under a hydrogen atmosphere overnight. The catalyst was filtered off and the filtrate concentrated in vacuo to give 470 mg of a crude solid that recrystallized from ethyl acetate/benzene to provide 100 mg (19% yield) of light yellow powder, mp 162-164° C.
