실험 절차

Benzyl 2-{[(benzyloxy)carbonyl]oxy}-5-chloro-1H-indole-1-carboxylate, intermediate 37 (5.00 g; 11.47 mmol) was treated with a solution of ammonia in dioxane (25.2 ml; 0.50 M; 12.6 mmol) and stirred overnight. Brine was added and the mixture extracted with ethyl acetate. The organic phase was dried (MgSO4) and removed in vacuo, to give a solid residue which was purified by recrystallisation (ethyl acetate), to give the title compound in 59% yield (HPLC purity 88%). MS (ESI+): 302.1; MS (ESI−): 300.1
