Reaktionsschritte

A mixture of 2-(4-methoxy-phenyl)-2-methyl-propylamine [172 mg, 0.96 mmol, Intermediate (35)], sodium bicarbonate (0.12 g), and 4-chloro-2-methoxy-6-(3-methoxy-phenyl)-pyrimidine [120 mg, 0.48 mmol, Intermediate (53)] in N-methylpyrrolidine (3 mL), is heated to 175° C. for 3 hours. The mixture is diluted with water, and extracted with ethyl acetate. The extracts are washed with water, dried over magnesium sulfate, filtered and concentrated. The residue is subjected to chromatography on silica gel eluting with 30% EtOAc in heptane to afford [2-methoxy-6-(3-methoxy-phenyl)-pyrimidin-4-yl]-[2-(4-methoxy-phenyl)-2-methyl-propyl]-amine [131 mg, 69%, Example 29]. LCMS: RT=2.73 minutes, MS: 394 (M+H). 1H NMR (300 MHz, CDCl3): □7.59 (1H, s), 7.51 (1H, d, J=7.8 Hz), 7.35-7.27 (3H, m), 6.96 (1H, dd, J=8.1, 2.4 Hz), 6.88 (2H, d, J=9 Hz), 6.31 (1H, s), 4.02 (3H, s), 3.86 (3H, s), 3.79 (3H, s), 3.62 (2H, brs), 1.4 (6H, s). IC50=792 nM
