反応手順

Intermediate 21 (0.35 g), methylamine (2.07 ml, 2M solution in tetrahydrofuran) were stirred together in tetrahydrofuran (15 ml) for 5 min, before sodium triacetoxyborohydride (1.32 g) was added. The reaction was stirred for 18 h, before water (10 ml) was added, and the tetrahydrofuran was removed in vacuo. The resulting slurry was washed with ethyl acetate (3×50 ml), and then basified to pH 11 using sodium hydroxide (2M). The aqueous was then re-extracted with ethyl acetate (3 ×50 ml). These combined organic extracts were washed with brine (100 ml), dried over magnesium sulphate (1 g), and the solvent removed in vacuo to yield the title compound as a colourless oil (0.13 g).
