Reaction Steps

A mixture of 3-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-benzenesulfonylchloride [0.05 g, Intermediate (10)] and triethylamine (0.064 mL) in dimethylformamide (5 mL) is cooled to 0° C. and the treated with a solution of methylamine in THF (5 mL, 2M). The mixture is allowed to reach room temperature overnight, poured into water (100 mL). This mixture is extracted twice with EtOAc (100 mL). The combined extracts are washed with water, dried over sodium sulfate, filtered and evaporated. The residue is subjected to chromatography on silica gel eluting with EtOAc to give 3-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-N-methyl-benzenesulfonamide [21.5 mg, Example 4(a)]. MS: 429 (M+H), 1H NMR [(CD3)2SO]: δ 8.4 (1H, s); 8.2 (1H, m); 7.85 (1H, d, J=3 Hz); 7.75-7.8 (1H, m); 7.5-7.6 (2H, m); 7.2 (2H, d, J=7 Hz); 6.95 (2H, d, J=7 Hz); 6.6 (1H, s); 3.9 (3H, s); 3.7 (3H, s); 3.5-3.6 (2H, m); 2.8 (2H, t); 2.45 (3H, d, J=2 Hz).
