実験手順

A mixture of the resulting thiourea (3.90 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.70 g, 8.89 mmol), and triethylamine (1.2 mL) in tetrahydrofuran (40 mL) was stirred at 50° C. for 2 hr. The mixture was diluted with saturated aqueous sodium hydrogen carbonate, and extracted with 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 diisopropyl ether to give the title compound as a colorless powder (2.20 g, 8.89 mmol, 57% in 2 steps).
