Reaction Steps

A solution of 3-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-benzenesulfonamide [100 mg, Example 3] in THF (10 mL) is treated with sodium hydride (20 mg). The mixture is stirred at 0° C. for 60 minutes, treated with methyl chloroformate (1 mL) and stirring is continued 0° C. for a further 60 minutes. The reaction mixture is poured into water and extracted twice with EtOAc (50 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 in heptanes (1:1, v/v) to give N-methoxycarbonyl-3-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-benzenesulfonamide [41 mg, Example 4(c)] as a solid. MS: 473 (M+H), 1H NMR [(CD3)2SO]: δ 12.2 (1H, s); 8.4 (1H, s); 8.15 (1H, m); 8 (1H, d, J=3 Hz); 7.65-7.8 (1H, m); 7.2 (2H, d, J=7 Hz); 6.9 (2H, d, J=7 Hz); 6.7 (1H, s); 3.9 (3H, s); 3.7 (3H, s); 3.5-3.6 (2H, m); 3.6 (3H, s); 2.8 (2H, t).
