실험 절차

To a solution of 3-(oxiran-2-ylmethoxy)benzaldehyde (1.0 g, 5.61 mmol) in MeOH (15 mL) was added cyclopentanamine (502 mg, 5.89 mmol) at room temperature. After 4 h, sodium borohydride (318 mg, 8.42 mmol) was added in portions and the mixture was stirred for another 1 h. The reaction mixture was quenched by adding aqueous 1 N HCl until the pH was adjusted to 4-5. The resulting solution was diluted with ethyl acetate, washed with water, dried over sodium sulfate, filtered and concentrated. The crude product was used in the next step without further purification. (1.1 g, yield 79%) MS (ESI+) e/z: 248.2 [M+1]+.
