YieldReaction ConditionsOperation in experiment
59.0% With hydrogenchloride; diisobutylaluminium hydride; In methanol; diethyl ether; dichloromethane; toluene; Step 2 Synthesis of 2-N-(1,1-dimethylethoxy-carbonyl)aminothiazole-4-carbaldehyde(22) (from ester 21) To a solution of 7.0 g (25.71 mmol) of ethyl ester 21 in CH2Cl2 (75 mL) were added 77 mL of diisobutylaluminum hydride (DIBAL-H, 1.0 M soln in toluene) for 20 minutes at -78 C. After stirring for 3 hours at that temperature, 30 mL of MeOH was added slowly to the reaction mixture, and then the reaction mixture was warmed to room temperature. Diethyl ether and 0.5 N HCl solution were added and the organic layer was separated. The solution was re-extracted with diethyl ether. The combined organic layers were washed with saturated NaHCO3 solution, dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by short flash column chromatography (silica, CH2Cl2:Hex:EtOAc=10:6:3 to CH2Cl2:EtOAc=1:1) to give 1.90 g (8.32 mmol) of solid aldehyde 22 in 32.4% yield and 3.5 g (15.20 mmol) of liquid alcohol 23 in 59.0% yield.
