YieldReaction ConditionsOperation in experiment
42% 400 mg (10 mmol) sodium hydroxide in 5.0 g water and 300 mg (5 mmol) acetic acid were added dropwise to a solution of 865 mg (5 mmol) <strong>[127294-75-1]rac-APIP dihydrochloride</strong> in 5.0 g water and the mixture was stirred for 10 min.1 146 mg (5 mmol) of Ps-L-Ala were added and the mixture was heated at 80C until a clear solutions was obtained. The solution was cooled slowly to r.t. and the suspension was stirred for 3 h. The formed solid was collected by filtration, washed with mother liquor, water, isobutanol, TBME and pentane (1 ml each) and dried to afford (R)-APIP-2 Ps-L-Ala-hbO as white solid. Yield: 1069 mg, 74% (based on the amount of enantiomer used). Enantiomeric ratio S/R = 3.71 : 96.29. The obtained acid addition salt was purified by recrystallization from 6.0 g of water. Yield: 605 mg, 42% (based on the amount of enantiomer used). Enantiomeric ratio S/R =0.03 : 99.97. Melting point: 180.6C. Specific rotation [a]D20=-4.4 (c=0.5, MeOH).
