실험 절차

A mixture of 8.8 g. of 50% NaH oil dispersion in 150 ml. of dry benzene was treated at 25° C. with 13.6 g. of ethylformate in 20 ml. of dry benzene under N2. Over a period of a half hour, 14.9 g. of 3-methyl-3-phenyl-2-butanone in 80 ml. of dry benzene was added at 0° C. After stirring at 40° C. for 4 hours, the mixture was diluted with 250 ml. of ether, treated with ice and acidified with hydrochloric acid. The acidic solution ws extracted with ether and the ether extract was washed with brine, sodiuim bicarbonate solution, washed again with brine and dried. The solvent was evaporated and the residue was distilled under reduced pressure to afford 14.8 g. of the title product as an oil, B. P. 83°-84°/0.2 mm., λmaxfilm 3.5 (broad) 5.75, 5.90, 6.12, 6.30, 6.70, 6.80, 6.95, 7.31, 7.94, 8.18, 9,38, 12,60, 13.05 and 14.28 μ.
