Procedure

Triethylamine (1.37 ml, 9.81 mmol) and chloroacetyl chloride (0.35 ml, 4.35 mmol) were added to a solution of the amine from example 4 (1.5 g, 3.95 mmol) in dichloromethane (50 ml), and the reaction stirred at room temperature for 2 hours. TLC analysis showed starting material remained, so additional chloroacetyl chloride (0.35 ml, 4.35 mmol) was added and the reaction was stirred for an additional 1.5 hours. The mixture was partitioned between dichloromethane and 2N sodium hydroxide solution and the layers separated. The aqueous phase was extracted with further dichloromethane and the combined organic solutions were washed with brine (50 ml), dried over magnesium sulphate, and evaporated under reduced pressure. The residual foam was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (95:5:0.5) to afford the title compound as a foam, 1.12 g.
