反応手順

1.65 g (7.16 mmol) of methyl 3-(5-methylpyrimidin-2-yl)benzoate, dissolved in 7 ml of THF, are added dropwise under a nitrogen atmosphere to a suspension of 272 mg (7.16 mmol) of lithium aluminium hydride in 7 ml of THF, and the mixture is stirred at room temperature for 24 h. 4 ml of a THF/water mixture (1:1) are subsequently added dropwise. A solution of 1.5 g of Na2CO3 in 4 ml of water is then added, the precipitate is filtered off with suction, and the residue is boiled with 2×THF/ethyl acetate and again filtered off with suction. The combined mother liquors are evaporated to dryness, the residue is dissolved in dichloromethane, and the solution is dried over sodium sulfate, filtered and again evaporated to dryness. The crude product is purified by column chromatography on silica gel; product: 500 mg; ESI: 201 (M+H).
