Hexane → HCID 86667471, compound

Participants

Reaction Steps

To a solution of 4-(4-chlorobenzyl)-N-methoxy-N-methyl-2-(pyridin-4-yl)thiazole-5-carboxamide (1.13 g, 3.02 mmol) in THF (36.8 mL) at −50° C. was added 1.0 M diisobutylaluminum hydride in hexane (15.1 mL, 15.1 mmol) and the resulting solution was stirred at −50° C. to −30° C. for 2 hours. The reaction was quenched with saturated ammonium chloride (10 mL) and allowed to warm to room temperature. Water (25 mL) was added and the mixture was extracted with ethyl acetate (2×40 mL). The combined organic layers were dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography (ethyl acetate/DCM=0/100→70/30) to give 699 mg of the title compound as a white solid (73% yield). LC/MS (FA) ES+ 315. NMR (300 MHz, CDCl3) δ: 10.16 (s, 1H), 8.78-8.76 (m, 2H), 7.85-7.83 (m, 2H), 7.30-7.25 (m, 4H), 4.47 (s, 2H).
