A solution of 4,6-dichloro-2-methoxypyrimidine [0.7 g, Intermediate (4)], 2-(3-fluoro-4-methoxy-phenyl)-ethylamine [0.66 g, Intermediate (3)] and sodium bicarbonate (0.88 g) in EtOH (25 mL) is heated at 80° C. for three hours and poured into water (400 mL). The resulting solid is filtered and air dried affording (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(3-fluoro-4-methoxyphenyl)-ethyl]amine [1.1 g, Intermediate (5)]. MS: 312 (M+H); 1H NMR (CDCl3): δ 6.9-7 (3H, m); 6.05 (1H, s); 3.95 (3H, s); 3.85 (3H, s); 3.6-3.7 (2H, m); 2.95 (2H, t).
