Versuchsvorschrift

To a suspension of lithium aluminium hydride 4.15 g in tetrahydrofuran 150 ml is added a solution of 2-methylthio-4-(3-chloro-4-methoxybenzylamino)-5-ethoxycarbonylpyrimidine (prepared in Example 67-(1)) 38.32 g in tetrahydrofuran 100 ml at 5-10° C. under ice cooling over a period of 1 hour. After addition the mixture is stirred for a hour without an ice bath. Water 4.15 ml is added under ice cooling thereto, followed by addition of 3N aqueous sodium hydroxide solution 4.15 ml. To the mixture is added water 4.15 ml three times and the mixture is stirred at room temperature for 1 hour. After treating with magnesium sulfate and filtration, the resulting cake-like substances are washed with terahydrofuran. The filtrate is concentrated in vacuo and triturated with ethyl acetate-isopropyl ether. The resulting crystals are filtered and washed well with isopropyl-ether to give 2-methylthio-4-(3-chloro-4-methoxybenzylamino)-5-hydroxymethylpyrimidine as a pale yellow crystalline powder.
