実験手順

A mixture of methyl 4-chloro-2-[(3-hydroxypropyl)amino]-3-{[(2-methoxy-4,6-dimethylpyrimidin-5-yl)carbamothioyl]amino}benzoate (13.1 g, 28.9 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (6.10 g, 31.8 mmol), and triethylamine (4.4 mL) in tetrahydrofuran (96 mL) was stirred at 60° C. for 2 hr. The mixture was diluted with saturated aqueous sodium hydrogen carbonate, and extracted with tetrahydrofuran/ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was washed with ethyl acetate/diisopropyl ether to give the title compound as a pale yellow powder (11.9 g, 28.3 mmol, 98%).
