PROCEDURE

实验过程

A solution of 41 g (0.165 mole) 2-amino-5-chloro-4'-hydroxybenzophenone in 800 ml of ether and 200 ml of water was cooled to 5°. The mixture was stirred while 20 ml (0.277 mole) of bromoacetyl bromide and a 20% solution of sodium carbonate were added alternately keeping the solution slightly basic. After 20 min. the reaction mixture was filtered to collect 60 g (about 100%) of product mp 201°-202°. Recrystallization from ethanol gave colorless prisms, mp 201°-203°.
