Procedure
2.95 g of 4-(2-methyl-1,3-thiazol-4-yl)benznitrile was dissloved in 100 ml of benzene and thereto was added dropwise a solution in toluene (1.5M) of diisobutylalminum hydride at the room temperature. Agitation was made for 1 hour. An excess amount of sodium sulfate dihydrate was added to the mixture and the resultant was stirred at the room temperature. A filtrate liquid thereof was concentrated and purified with column chromatography using silica gel and dichloromethane to obtain 1.95 g of the intended compound with a yield of 68%.
