実験手順

Benzyl 2-(di-tert-butoxyphosphoryloxy)ethyl(ethyl)carbamate (INTERMEDIATE 48, 0.9 g, 2.17 mmol) was dissolved in methanol (5 ml), and 5% Pd on charcoal (0.10 g) was added. The reaction mixture was stirred at r.t under a hydrogen atmosphere overnight. The reaction mixture was filtered and concentrated in vacuo to give the title compound (0.57 g, yield: 94%).
