Reaction Steps

A solution of [2-(3,4-dimethoxy-phenyl)-ethyl]-[6-(3,4-dimethoxy-phenyl)-2-methanesulfonyl-pyrimidin-4-yl]-anine [200 mg, 0.42 mmol, Intermediate (33)], and isopropyl alcohol (1 mL) in N,N′-dimethylformamide (2 mL) at 0° C. is treated with sodium hydride (60%, 102 mg, 12.7 mmol). After 1 hour at 20° C., the mixture is concentrated, and extracted twice with EtOAc (50 mL). The combined extracts are washed twice with water, dried over magnesium sulfate, filtered, and concentrated. The residue is subjected to chromatography on silica gel eluting with 60% EtOAc in heptane to afford [2-(3,4-dimethoxy-phenyl)-ethyl]-[6-(3,4-dimethoxy-phenyl)-2-isopropoxy-pyrimidin-4-yl]-amine [0.15 g, 79%, Example 17(a)] LCMS: RT=2.57 minutes, MS: 454 (M+H). 1H NMR (300 MHz, CDCl3) □7.64 (1H, d, J=2.1 Hz), 7.55 (1H, dd, J=8.4, 2.4 Hz), 6.91 (1H, d, J=8.4 Hz), 6.86-6.76 (3H, m), 6.3 (1H, s), 5.43-5.34 (1H, m), 4.83 (1H, brs), 3.99 (3H, s), 3.95 (3H, s), 3.89 (3H, s), 3.75-3.65 (2H, m), 2.91 (2H, t, J=6.9 Hz) 1.45 (6H, d, J=6 Hz).
