Komponenten

Versuchsvorschrift

1.76 ml (24.16 mmol) of thionyl chloride are added to 2 g (9.29 mmol) of [4-(benzyloxy)pyridin-2-yl]methanol [described in J. Org. Chem., (1996), 61(8), 2624] in 46 ml of dichloromethane. The reaction medium is stirred at ambient temperature for 18 hours and then concentrated under reduced pressure. The residue obtained is taken up in a saturated aqueous sodium carbonate solution and then extracted with dichloromethane. The organic phase is dried over sodium sulfate and then concentrated under reduced pressure. 2.1 g of a brown oil are collected. Mass spectrometry (ES+Mode): MH+=234
