A solution of 5.9 g (23.85 mmol) of 4-methyl-2-phenyl-thiazole-5-carboxylic acid ethyl ester in 30 ml of absolute THF was added to a suspension of 1.1 g (29 mmol) of lithium aluminium hydride in 20 ml of THF, under an argon atmosphere at 0-5° C. Afterwards, the mixture was stirred at ambient temperature for 1 hour. Then, a small amount of water was added cautiously, followed by 50 ml of ethyl acetate and 20 g of anhydrous sodium sulfate and stirring was continued for 0.5 hours. Then, the reaction mixture was filtered, the filtrate was evaporated, leaving 3.85 g (78.6% of theory) of (4-methyl-2-phenyl-thiazol-5-yl)-methanol as yellow solid.
