A mixture of compound (6-chloro-5-nitro-pyrimidin-4-yl)-(4-methanesulfonyl-phenyl)-amine (400 mg, 1.22 mmol), 4-(4-trifluoromethoxy-phenoxy)-piperidine (399 mg, 1.34 mmol) and potassium carbonate (336 mg, 2.44 mmol) in DMF (8 ml) was heated in an oil bath at 60° C. for 2 hours. The crude mixture was cooled to 0° C. and quenched with water. The solid was filtered off, rinsed with water and dried in vacuum oven to give product B119 as a yellow solid (604 mg, 90%). 1HNMR (CDCl3, 400 MHz) d 2.01-2.08 (m, 4H), 3.06 (s, 3H), 3.64-3.66 (m, 2H), 3.73-3.75 (m, 2H), 4.62-4.66 (m, 1H), 6.93 (d, 2H), 7.17 (d, 2H), 7.93 (dd, 4H), 8.21 (s, 1H), 10.2 (s, 1H). Exact mass calculated for C23H22F3N5O6S 553.1, found 554.3 (MH+).
