Participants

Reaction Steps

The tosylate used as starting material was prepared by treating a solution of N-[3,5-dimethoxy-4-(2-hydroxyethoxy)phenyl]-4-(3-methoxyphenylsulphanyl)-2-pyrimidineamine (2.0 g, 4.3 mmol) in pyridine (6 ml) with p-toluenesulphonyl chloride (3.28 g, 17.2 mmol) at room temperature for 2 h. Water (25 ml) was added to the reaction followed by acidification with 2M hydrochloric acid, and this was extracted with ethyl acetate (100 ml). The organic phase was washed with 2M hydrochloric acid (100 ml) and saturated aqueous Na2CO3 (100 ml), dried (MgSO4) and concentrated under reduced pressure to give the desired product as a light brown oil (2.31 g). δH (CDCl3) 8.04 (1H, d, J 5.4 Hz), 7.80 (2H, d, J 8.3 Hz), 7.39-7.30 (3H, s), 7.20-7.13 (2H, m), 7.03-6.99 (2H, m), 6.86 (2H, s), 6.22 (1H, d, J 5.4 Hz), 4.31 (2H, t, J 5.6 Hz), 4.13 (2H, t, J 5.6 Hz), 3.81 (3H, s), 3.77 (6H, s) and 2.43 (3H, s).
