New Compounds. Di-(p,p-dichlorobenzohydryl) Ether

Abstract

New Compounds 693 centrated at reduced pressure and washed with aqueous sodium bicarbonate and with water, and dried over anhydrous magnesium sulfate. The residue (4.4 g., 82% yield) left by complete removal of solvent was relatively pure ester, m. p. 40-45°. Three recrystallizations from ether-petroleum ether gave 3.0 g. of pure material of constant melting point (41-43°).
