3-Chloro-4-fluoroaniline → 2-(3-Chloro-4-fluoro-phenylamino)-4-trifluoromethyl-pyrimidine-5-carboxylic acid cyclopentylmethyl-amide

Participants

Reaction Steps

2-Chloro-4-trifluoromethyl-pyrimidine-5-carboxylic acid cyclopentylmethyl-amide (116 mg Example 183a), 3-chloro-4-fluoroaniline (ex-Aldrich, 275 mg), and 1,4-dioxan (1.2 ml) were stirred at 100° C. under nitrogen for 6 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 brine, and dried (Na2SO4). The solution was evaporated in vacuo to give the title compound (104 mg).
