This compound was prepared according to the procedure used in Example 84. A mixture of 9.9 g (0.05 mole) of 3-hydroxybenzophenone and 4.4 ml (7.1 g, 0.0505 mole) of chlorosulfonyl isocyanate in 75 ml of toluene gave a solid as residue. This residue was recrystallized successively from benzene and then methylene chloride to yield 4.2 g (30%) of the title compound as a white solid, mp 72°-74° C.
