Reaction Steps

Into a 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of ethyl 3-(4-ethylphenyl)-5-(prop-1-en-2-yl)-1,2-thiazole-4-carboxylate (280 mg, 0.93 mmol, 1.00 equiv) in toluene (6 mL). DIBAL-H (1.32 g, 2.50 equiv) was added at −78° C. The resulting solution was stirred for 4 h at −78° C. The reaction was then quenched by the addition of 5 mL of water. The resulting solution was extracted with 200 mL of ethyl acetate. The organic layer was washed with 1×30 mL of brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The crude product was purified by TLC method with petroleum ether/ethyl acetate (3:1). This resulted in 305.3 mg (crude) of [3-(4-ethylphenyl)-5-(prop-1-en-2-yl)-1,2-thiazol-4-yl]methanol as yellow oil. Mass spectrum (ESI, m/z): Calcd. for C15H17NOS, 260.4 (M+H). found 260.4.
