Sodium Sulfate → {3-[5-(3-Dimethylaminopropoxy)pyrimidin-2-yl]phenyl}methanol

Participants

Reaction Steps

200 ml of a 1 M solution of diisobutylaluminium hydride in THF are added dropwise with stirring to a solution, kept under nitrogen, of 12.6 g (40.0 mmol) of methyl 3-[5-(3-dimethylaminopropoxy)pyrimidin-2-yl]benzoate in 200 ml of THF. After the mixture has been stirred at room temperature for 1 hour, 10 ml of a saturated aqueous sodium sulfate solution are added dropwise. The resultant precipitate is filtered off with suction and washed with dichloromethane. The filtrate is dried over sodium sulfate and evaporated. The residue is taken up in a mixture of diethyl ether and petroleum ether. The resultant precipitate is filtered off with suction, washed with petroleum ether and dried in vacuo: {3-[5-(3-dimethylaminopropoxy)pyrimidin-2-yl]phenyl}methanol as colourless crystals; m.p. 95-97° C.; ESI 288 (M+H); HPLC: Rt=2.35 min (method B).
