Ethyl 2-isopropylthiazole-4-carboxylate → 2-Isopropylthiazole-4-carbaldehyde

Participants

Reaction Steps

A solution of ethyl 2-isopropylthiazole-4-carboxylate (1 mmol)in 50 ml of dry dichloromethane was cooled to -78° C. under N2 atmosphere and treated dropwise with 1.2 mmol of diisobutylaluminum hydride (1.5M in toluene). The resulting solution was stirred for 0.5 h, quenched with aqueous Rochelle salts, extracted with dichloromethane, dried over Na2SO4, and concentrated in vacuo to provide the crude desired compound.
