Reaction Steps
Sodium hydride (4 eq, 2.66 mmol, 0.13 g of a 50 wt-% suspension in oil) was suspended in THF (2 mL) and cooled to 0° C. 2-methoxy ethanol (3 eq, 1.99 mmol, 0.15 g) and 15-crown-5-ether (1 drop) were added. 1-(3-Fluorobenzyl)-3-(3-(chloromethyl)-1,2,4-thiadiazol-5-yl)urea (Intermediate XXV) was added and the mixture was stirred over night with temperature allowed to rise to room temperature. Dichloromethane (50 mL) was added. The mixture was washed with water (2×10 mL), dried (Na2SO4), filtered and concentrated in vacuo. The crude material (0.2 g of an oil) was further purified by preparative HPLC to give 0.101 g. 1H-NMR (300 MHz, CD3OD): δ 7.34 (m, 1H), 7.14 (d, 1H), 7.07 (d, 1H), 6.99 (m, 1H), 4.58 (s, 2H), 4.45 (s, 2H), 3.70 (t, 2H), 3.56 (t, 2H), 3.30 (s, 3H).
