Reaction Steps

2-Chloro-4-(N-4,4,4,-trifluorobutyl-2-fluoro-5-methylanilino)pyrimidine (215 mg, 0.62 mmol) was dissolved in n-butanol (2 ml) and sulphanilamide (85 mg, 0.50 mmol) was added. The resulting suspension was treated with methanol until all the solid dissolved. The reaction mixture was heated at 95° C. for 12 hours and allowed to cool to ambient temperature. The solid that had precipitated was collected by filtration, washed with a small volume of methanol and dried in vacuo to yield a white solid (132 mg). NMR (400 MHz@373K): 1.85 (m, 2H), 2.31 (m, 2H), 2.35 (s, 3H), 3.97 (t, 2H), 6.04 (d, 1H), 7.29 (m, 3H) 8.02 (d, 1H), 10.00 (br s, 1H); MS (M+H)+: 484.4.
