Procedure
2-Chloro-4-trifluoromethyl-pyrimidine-5-carboxylic acid cyclopentylmethyl-amide (100 mg Example 183a), 2-chloro-5-fluoroaniline (ex-Fluorochem, 237 mg), and 1,4-dioxan (1 ml) were stirred at 100° C. under nitrogen for 18 h. The cooled reaction mixture was evaporated in vacuo, treated with ethyl acetate (5 ml), washed with aqueous 2M hydrochloric acid (2×3 ml), followed by water (2×3 ml), and dried (Na2SO4). The solution was evaporated in vacuo and the residue purified by mass directed auto-preparative purification to give the title compound (35 mg).
