Procedure

A solution of [2-methanesulfonyl-7-(3-trifluoromethyl-pyridin-2-yl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepin-4-yl]-(4-trifluoromethyl-phenyl)-amine (Example 53; 44 mg, 0.08 mmol) and NaOMe (100 mg, 0.25 mmol) in MeOH (1.5 mL) was heated at 60° C. for 1 h. The mixture was cooled, acidified with HOAc (3 drops), and directly purified using Preparative HPLC (conditions as in Example 54) to give the title compound (35 mg, 89%). MS (ESI): mass calcd. for C22H19F6N5O, 483.15; m/z found, 484.8 [M+H]+. 1H NMR (CDCl3): 9.63 (s, 1H), 8.39 (d, J=3.3 Hz, 1H), 7.89 (d, J=7.7 Hz, 1H), 7.73 (d, J=8.5 Hz, 2H), 7.63 (d, J=8.5 Hz, 2H), 7.06-7.02 (m, 1H), 3.88 (s, 3H), 3.50-3.44 (m, 4H), 3.26-3.22 (m, 2H), 3.11-3.07 (m, 2H).
