Reaction Conditions

Reaction Steps

To a solution of [4-(2,6-dimethyl-4-pyridyl)-5-(3-methylphenyl)-1,3-thiazol-2-yl]amine (0.50 g, 1.7 mmol) in N,N-dimethylacetamide (20 mL) was added phenyl isocyanate (0.28 mL, 2.6 mmol), and the mixture was stirred for 14 hours at 80° C. Aqueous sodium hydrogen carbonate was poured into the reaction mixture, and extracted with ethyl acetate. The extracts were washed with brine, then, dried to be concentrated. The residue was purified by silica gel column chromatography (hexane-ethyl acetate=1:1). The resulted crude crystal was recrystallized from ethyl acetate-hexane to obtain a title compound (0.34 g, yield 48%).
