Procedure

A reaction procedure similar to step (2) of Example 1 was followed using 18.8 grams of sodium hydroxide, 13 grams of water, 86 ml of methanol, 50 grams (0.12 mol) of 4,4'-bis[(dimethylmethoxysilyl)methoxy]benzophenone resulting from step (1), 120 ml of ethanol, 18.8 grams of sodium hydroxide, 86 ml of water, 137 grams of potassium dihydrogen phosphate, and 2,200 grams of ice water. Recrystallization from toluene gave 28.8 grams (yield 61%) of pale yellow crystals.
