Reaction Steps

A solution of 3-(2-chloro-6-fluorophenyl)-5-[5-(4-hydroxyphenyl)-4-methylthien-3-yl]-1-methyl-1H-1,2,4-triazole (97 mg, 0.2 mmol) in dry THF (2 mL) was cooled to −3° C. and treated with sodium hydride (95% suspension in mineral oil, 9 mg, 0.4 mmol). After stirring for 5 minutes, iodopropane (62 mg, 0.4 mmol) was added and the reaction was allowed to stir at room temperature for 16 hours. An additional batch of sodium hydride (9 mg, 0.4 mmol) and iodopropane (62 mg, 0.4 mmol) was added and the reaction heated to 45° C. After dilution with water (5 mL), the product was extracted with ether (3×5 mL). The combined ethereal extracts were washed with water (2×5 mL) and brine (10 mL), dried over magnesium sulphate and concentrated. Column chromatography gave the product (101 mg, 93%) as a colorless glass: 1H NMR (CDCl3) δ 7.49 (s, 1H), 7.27-7.41 (m, 4H), 7.12 (t, 1H), 6.98 (d, 2H), 4.04 (s, 3H), 3.99 (t, 2H), 2.32 (s, 3H), 1.85 (m, 2H), 1.08 (t, 3H); EI/MS 441 m/e (M+1).
