Reaction Steps

A mixture of Intermediate 29 (0.0134 g), {4-[(methylsulfonyl)amino]phenyl}acetic acid (0.0137 g, known compound WO 9929655 A1), 1-hydroxybenzotriazole (0.0097 g) and N,N-diisopropylethylamine (0.01 ml) in N,N-dimethylformamide (0.5 ml) was treated with a solution of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.00138 g) in N,N-dimethylformamide (0.5 ml). The mixture was stirred at 20° C. for 24 h. The mixture was partitioned between dichloromethane (4 ml) and saturated aqueous sodium hydrogen carbonate (4 ml). The phases were separated and the organic phase applied to an ion exchange cartridge (2 g Isolute SCX, prewashed with methanol). The SCX cartridge was eluted with methanol (10 ml) followed by 10% 0.880 ammonia in methanol (10 ml) and the appropriate fractions were concentrated in vacuo to give the title compoundas a colourless (0.0174 g).
