실험 절차

Raney® nickel (170 mg) was added to a solution of tert-butyl 2-{[3-(cyanomethyl)benzyl]oxy}ethylcarbamate (preparation 104) (654 mg, 2.26 mmol) in ethanolic ammonia solution (15 ml), and the mixture hydrogenated at 60 psi and room temperature for 24 hrs. The reaction mixture was filtered through Arbocel®, and the filtrate evaporated under reduced pressure. The residue was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (90:10:1) to afford the title compound, (536 mg, 80%).
