After 5 min methyl chloroacetate (0.29 g) was added and the mixture was stirred for 2 h. Aqueous ammonia (2M, 10 ml) was added and the solvent was removed under vacuum. The residue was purified by column chromatography on silica eluting with cyclohexane:ethyl acetate (2:1 to 1:1) to give the title compound (0.56 g).
