실험 절차

A solution of the product from example 1, step (c) (0.25 g) and 2-amino-2-methyl-1,3-propanediol (0.28 ml) in N-methylimidazole (1 ml) was heated in a microwave at 160° C. for 95 minutes. After cooling, the reaction mixture was partitioned between ethyl acetate and saturated aqueous ammonium chloride. The organic phase was dried over magnesium sulphate, filtered and evaporated to give a brown oil which was purified by silica gel flash column chromatography, eluting with 10:1 dichloromethane:methanol to give the title compound as a pale brown solid (0.031 g).
