실험 절차

2-(2-Pyridyl)ethyl Tributylstannyl Ether is prepared from 59.6 gm (0.1 mole) of bis(tributyltin) oxide and 24.6 gm (0.2 mole) 2-(β-hydroxyethyl)pyridine in 200 ml benzene. This is stirred and heated to reflux in a system that contains a Dean-Starke tube. After 30 minutes refluxing water began to collect in the Dean-Starke tube and after refluxing 22 hours a total of 2.0 ml of water (theory 1.8 ml) had collected. This is evaporated on a rotating evaporator to provide 82.6 gm of straw colored liquid, which fractionated at reduced pressure. 66.4 gm. of a straw colored liquid are collected at 155°-158° C. at 0.5 mm. (Percent yield - 80.6). Infrared spectral analysis shows this to be the desired ether.
