	With N-Bromosuccinimide; 2,2'-azobis(isobutyronitrile); In tetrachloromethane;Reflux; Irradiation;	General procedure: Step 1 and 2: To isobenzofuran-1(3H)-one (7.7 mmol, 1 equiv) in 100 mL oftetracarbonchloride was added N-bromosuccinimide (9.24 mmol, 1.2 equiv.),azobisisobutyronitrile (0.77 mmol, 0.1 equiv.). The resulting mixture was refluxed underirradiation with 200 W lamp for 6 h. The solvent was evaporated and water (50 mL) wasadded and the resulting mixture refluxed for 2 h. The reaction mixture was then cooled toroom temperature and kept at -10 C overnight. The precipitate was filtered and dried invacuum to give the desired product.

The pH was maintained at 1.8 on the pH meter by dropwise addition of 5N hydrochloric acid. The acetone was removed in vacuo and the aqueous solution extracted with ethyl acetate (30 ml.). The aqueous solution was then salted with solid sodium chloride and the resulting oil separated, dissolved in acetone (50 ml.) and dried over anhydrous magnesium sulphate. The solution was poured into vigorously stirring dry ether (3 lit.) and the solid filtered, washed with ether and dried to give the 6-chlorophthalide ester of 6-(D(-)α-aminophenylacetamido)penicillanic acid, hydrochloride.

	With ammonium chloride; In diethyl ether; benzene;	EXAMPLE 13 4',5-Dichloro-2-hydroxymethylbenzophenone Magnesium turnings (2.5 g.) are suspended in 20 ml. of ethyl ether and 19 g. of 4-chlorobromobenzol in 35 ml. of ethyl ether is added to the mixture which is then refluxed for two hours. After cooling to room temperature, 16.8 g. of <strong>[19641-29-3]6-chlorophthalide</strong> in 100 ml. of anhydrous benzene is added and the solution is heated at 50-60 C. for about 1 hour. The reaction mixture is cooled and stirred with 50 ml. of aqueous 20% ammonium chloride. The organic phase is separated and washed with aqueous sodium bicarbonate, then with water. Evaporation yields 24 g. of crude titular product which is hydrogenated according to the procedure of the foregoing example to give the corresponding benzhydrol.
