Procedure

NaOH (2M, 1.488 mL, 2.98 mmol) was added in one portion to a mixture of N′-{4-[1-(benzenesulfonyl)indol-3-yl]-5-chloropyrimidin-2-yl}-4-methoxy-6-(1-methyl-3,6-dihydro-2H-pyridin-4-yl)benzene-1,3-diamine (Intermediate 8, 283 mg, 0.47 mmol) in CH3OH (6 mL) at r.t. under N2. The resulting solution was stirred at reflux for 0.5 h. Dry ice was then added and the resulting mixture was concentrated in vacuo. The resulting residue was triturated with CH2Cl2/CH3OH (4:1, 20 mL), filtered and the filtrate was concentrated in vacuo to give a residue. Purification by FCC, eluting with 2-10% methanolic ammonia in CH2Cl2 gave the title compound (102 mg, 47%) as a pale yellow powder; 1H NMR: 2.30 (3H, s), 2.41 (2H, s), 2.60 (2H, t), 3.02 (2H, d), 3.70 (3H, s), 4.27 (2H, s), 5.73 (1H, s), 6.65 (1H, s), 7.08 (1H, t), 7.17-7.23 (1H, m), 7.26 (1H, s), 7.48 (1H, d), 8.18 (1H, s), 8.38 (1H, s), 8.41 (1H, d), 8.49 (1H, s), 11.85 (1H, s); m/z: ES+ MH+ 460.
