Procedure

A mixture of the product of Example 1, Step 6 (0.1 g, 0.29 mmol) and methane sulphonyl chloride (0.023 ml, 0.3 mmol) in dichloromethane (3 ml) was stirred at room temperature for 2 hours. The reaction was then poured into ethyl acetate, washed with water and aqueous sodium hydrogen carbonate solution, dried (MgSO4) and concentrated in vacuo. The crude residue was then purified by silica gel chromatography eluting with a 1:9:90 mixture of 0.88 ammonia solution:methanol:dichloromethane to give the title compound (0.075 g, 61%) as a yellow solid; MS(AP+) m/e 425 [M+H]+.
