실험 절차

Racemic (tetrahydrofuran-3-yl)methanamine (3.84 g, 38.0 mmol) and diisopropylethylamine (13.26 ml, 76 mmol), were dissolved in dichloromethane (100 ml) and cooled to 0° C. The mixture was treated dropwise via an addition funnel with benzyl carbonochloridate (6.19 ml, 41.8 mmol) dissolved in 30 ml dichlormethane. After the addition the cooling bath was removed and the homogeneous solution was stirred at ambient temperature overnight. The reaction mixture was partitioned between water and ethyl acetate and the separated aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over magnesium sulfate, filtered and concentrated. Chromatography provided the title compound.
