실험 절차

1-(Phenylmethyl)4-(hydroxymethyl)-pyridinyl chloride(0.87 mol) was dissolved in methanol (2200 ml) and cooled to −20° C. Sodium borohydride (1.75 mol) was added portionwise under a nitrogen atmosphere. The reaction mixture was stirred for 30 minutes and water (200 ml) was added dropwise. The reaction mixture was partially evaporated, water was added and the reaction mixture was extracted with DCM. The organic layer was separated, dried, filtered and evaporated. The residue was purified over silica gel (eluent: DCM), yielding 155 g of 1,2,3,6-tetrahydro-1-(phenylmethyl)4-pyridinemethanol.
