To 4 liters of absolute methyl alcohol was added 300 grams (4.5 moles) of 85% potassium hydroxide pellets with mechanical stirring. The amount of 618 grams (2.7 moles) of 4-(chloromethyl)benzophenone was added to the resulting warm solution. The reaction mixture was refluxed for three hours, filtered with suction, and concentrated. Water was added and the lower oily layer was separated and distilled to provide 530 grams (88.5% yield) of 4-(methoxymethyl)benzophenone as an almost colorless liquid (b.p. 140° C., 0.20 mm Hg). The infrared spectrum revealed a carbonyl band at 1660 cm-1. Ultraviolet analysis revealed λ max (ε) at 256 nanometers (18,380).
