実験手順

[5-(3-Hydroxy-propyl)-pyridin-2-yl]-thiourea (7-4), 2.20 g (10.4 mmol) was stirred in 20 mL EtOH. (1-Bromo-2,2-dimethoxy-ethyl)-benzene (3.83 g, 15.6 mmol) was added, dissolved in 12 mL EtOH. The reaction was heated to reflux. After 30 min, 8 mL of concentrated HCl (aq) was added. After 7 h the reaction was cooled to RT, and diluted with water. Na2CO3 (s) was added to pH 9. The resulting precipitate was filtered, and washed with water. To solid was added ether, the mixture was sonicated and filtered, washing with ether. Afford the titled compound as a white solid. 1H NMR (CDCl3): δ 8.74 (bs, 1H), 8.25 (d, 1H, J=2.2 Hz), 7.57 (dd, 2H, J=1.7, 9.0 Hz)7.49 (dd, 1H, J=2.4, 8.4 Hz), 7.38 (t, 2H, J=7.7 Hz), 6.83 (d, 1H, J=8.2 Hz), 3.71 (m, 2H), 2.70 (t, 2H, J=6.7 Hz), 1.89 (m, 2H). Mp 153-154° C. MS [M+H]+=312.2.
