実験手順

1-Dimethylamino-2-Propyl Tributylstannyl Ether is prepared from 89.4 gm (0.15 mole) bis(tributyltin) oxide and 30.9 gm (0.3 mole) 1-dimethylamino-2-propanol in 200 ml benzene. This is stirred and heated to reflux in a system that contains a Dean-Starke tube. After refluxing 23 hours a total of 2.6 ml of water (theory 2.7 ml) had collected in the Dean-Starke tube. The solvent is stripped off on a rotating evaporator to provide 111.0 gm of yellow liquid. This is fractionated at reduced pressure with collection at 167°-175° C. at 0.5 mm of 63.4 gm of straw colored liquid. (Percent yield - 54). Infrared spectral analysis shows this liquid to be the desired ether.
