Procedure
To a solution of 2-chloro-4-trifluoromethyl-pyrimidine-5-carboxylic acid cyclohexylmethyl-amide (Example 166a) (50 mg) in 1,4-dioxan (1 ml) was added 2,3-difluoroaniline (Aldrich) (113 mg) and the mixture was stirred at reflux for 47 hours using a Radleys Greenhouse Parallel Synthesiser. The dioxan was removed using a nitrogen blow down unit. The residue was taken up into methanol (0.5 ml) and dimethylsulfoxide (0.5 ml) and purified using a mass directed auto-preparative system to give the title compound (16 mg)
