Participants

Reaction Steps

To a solution of 4-iodo pyridine (0.142 g, 0.635 mmol) in THF (12 mL) at −78° C. was added n-BuLi in hexane (1.6 M, 0.582 mL, 0.8474 mmol) and the mixture stirred for 30 min. A solution of 1-(5-(4-fluorophenyl)-1,3,4-thiadiazole-2-yl)propan-1-one (0.1 g, 0.4237 mmol) in THF (8 mL) was added to above solution at −78° C. and the mixture stirred for 1 hour at −78° C. The reaction mixture was quenched with saturated ammonium chloride solution (20 mL) and diluted with water (25 mL). The reaction mixture was extracted with ethyl acetate (200 mL), dried over sodium sulfate and concentrated under reduced pressure to obtain crude product. The crude compound was purified by preparative TLC (using 5% methanol and dichloromethane) to afford 1-(5-(4-fluorophenyl)-1,3,4-thiadiazol-2-yl)-1-(pyridin-4-yl)propan-1-ol as white solid (22 mg, 17% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.55 (d, 2H), 8.0-7.96 (m, 2H), 7.56 (d, 2H), 7.35 (t, 2H), 7.06 (s, 1H), 2.40-2.30 (m, 2H), 0.80 (t, 3H); LC-MS m/z calculated for [M+H]+ 316.08, found 316.1.
