YieldReaction ConditionsOperation in experiment
60.0 g 4,4?-Bis(2-bromoacetyl)biphenyl bOg was added to methylene dichloride (l000ml) andstirred to get solution. Boc-L-Proline (120g) was added to it. Diisopropylethylamine68.5g was added to the reaction mass at 15-25C. The reaction mass was stirred for about4 to 5h. The reaction mass was quenched by adding water. The aqueous layer was separated and organic layer was washed with aqueous acetic acid solution (Conc HC1 also can be used instead of acetic acid) till pH of aqueous layer was between 4-6. Theorganic layer was washed with water and distilled under vacuum to get a residue. The residue was dissolved in toluene and toluene solution was used further. Ammonium acetate 390g was added to the toluene solution and the reaction mass was stirred. The reaction mass heated to 95-105C and maintained till completion of reaction. After completion of the reaction, the reaction mass was cooled to 50-60C, methanol wasadded and the reaction mass cooled to 20-30C and stirred for 2 to 3 hours. The solid was filtered and washed with toluene. Purity of crude:- 93.92%.Crude wet cake was stirred in mixture of toluene, methanol and acetic acid and the reaction mass was heated to 60- 70C, water was added to reaction mass at 60-70C and the reaction mass cooled to 20-30C and stirred. The solid obtained was filtered and washed with toluene and then withwater. Wet solid was dried. Purity - 97.04%. The above purification was repeated to obtain 60.Og of the title compound in a purity of 98.97%.
