Procedure: To a solution of 2-phenyl-ethenesulfonic acid amide (500 mg, 2.7 mmol) in dioxane (25 ml) sodium hydride (197 mg, 55% dispersion in mineral oil) were added and the mixture was stirred at room temperature for 30 minutes. 4-Chloro-2-fluoro-benzoyl chloride (527 mg, 2.7 mmol) were added and the mixture was stirred at room temperature overnight. After addition of water (50 ml) the pH was adjusted to 7 with 1 N HCl and the mixture was extracted with ethyl acetate (3 times 50 ml). The combined organic phases were dried over Na2SO4 and concentrated in vacuo. Preparative HPLC (RP18, methanol-water-gradient) returned the title compound (730 mg, 79% yield) as a white solid. the mixture was stirred at room temperature overnight the mixture was extracted with ethyl acetate (3 times 50 ml) The combined organic phases were dried over Na2SO4 concentrated in vacuo

Procedure: 6-Chloro-N4-(4-chlorophenyl)-pyrimidine-4,5-diamine I-(1A-1)a (6.6 g, 26 mmol) in pyridine (30 ml) was cooled to 0° C. and to it was added 4-chloro-2-fluorobenzoyl chloride (5 g, 26 mmol). The reaction was then allowed to warm to ambient temperature overnight. The heterogeneous reaction was diluted with ethanol (50 ml) and the resulting solid collected by filtration. The solids were slurried in toluene, which was then removed under reduced pressure to remove residual ethanol. The solid was slurried in diethyl ether and then collected by filtration to give I-(7A-91)a (8.3 g, 78%): +ACPI MS (M+1) 409.0; 1H NMR (400 MHz, CD3OD) δ 10.60 (s, 1H), 10.10 (s, 1H), 9.19 (s, 1H), 8.74 (t, J=8.1 Hz, 1H), 8.46–8.40 (m, 3H), 8.28 (dd, J=8.7, 2.1 Hz, 1H), 8.20 (d, J=8.7 Hz, 2H).
