실험 절차

A solution of Stage 3 (28.6 g; assume 24.7 mmol) in methanol (515 ml) was treated with sodium methoxide (0.44 g, 8.13 mmol) for 90 minutes before being treated with a further portion of sodium methoxide (0.44 g, 8.13 mmol). After 30 minutes Dowex 50 [H+] was added to neutralise the solution. The resin was filtered off and the filtrate was evaporated to leave the title Compound as a foam (24 g).
