反応手順

To a mixture of lithium aluminum hydride (4.5 g, 119 mmol) in ice cold tetrahydrofuran (100 mL) was added ethyl 2-dimethylaminomethylthiazole-4-carboxylate (8.5 g, 39.7 mmol in 40 mL of tetrahydrofuran) dropwise over 40 min maintaining an internal temperature of 5-10C. The mixture was stirred at this temperature range for 90 min. The reaction was carefully quenched with saturated aqueous ammonium chloride (30 mL). The resulting gray slurry was stirred 15 min and filtered through celite. The pad was well washed with ethyl acetate. The filtrate was washed with brine and dried over sodium sulfate. Concentration of this organic solution gave 4.2 g (62%) of 2-dimethylaminomethyl-4-hydroxymethylthiazole as an amber oil. The material was used without further purification.
