실험 절차
The compound prepared in Example 1 (1.00 g) was dissolved in 150 ml of dry dimethylformamide, and 2.08 g (7.32 mmol) of N,N′-dicyclohexyl-4-morpholine-carboxamidine and 2.75 g (18.3 mmol) of chioromethyl pivalate were added thereto. When the reaction mixture became homogeneous after about 1 hour, it was stirred for 5 days at room temperature. The reaction solution was filtered, the filtrate was concentrated under reduced pressure, and the residue was fractionated with 50 ml of water and 50 ml of toluene to separate the organic layer. The aqueous layer was extracted twice with 50 ml of toluene. The combined organic layers were concentrated under reduced pressure. The residue was purified by column chromatography (eluent: methanol/dichloromethane=1/20, v/v) to give 0.59g (Yield 32%) of the title compound as a white solid.
