実験手順

To a solution of 83.3 g. (0.318 mole) triphenyl-phosphine in 200 ml. benzene was added, in four portions, 80 g. (0.318 mole) of iodine. The resultant mixture was stirred 3 hours and then 50 ml. (0.618 mole) of pyridine was added followed by the slow addition of 32 g. (0.192 mole) of 3-benzyloxypropanol in 250 ml. of benzene. The reaction was stirred 15 hours longer and then diluted with 40 ml. of methanol. The mixture was filtered through diatomaceous earth and the filtrate evaporated to an oil. Distillation of the crude oil yielded 28 g. (53%) of the title compound as an oil.
