実験手順
2.16 g (0.01 mole) of 4-hydroxy-4'-chlorobenzophenone and 1.2 g (0.015 mole) of pivaloyl chloride in solution were warmed to 50° C. for 3 hrs in 60 mls of dry pyridine with a drying tube attached. The solvent was removed via rotary evaporator and H2O added. The product was filtered and recrystallized from ethanol; 2.3 g (73%) yield; M.P.~113°-114° C.
