YieldReaction ConditionsOperation in experiment
With sodium hydroxide In DMF (N,N-dimethyl-formamide); water; ethyl acetate at 0 - 25℃; for 6.5 - 8h; 6.3 Separately, 23.5 g of N-Methylmorpholine is added to a mixture of 33.1 g of 4-Amino-chloro-benzoic acid 34.4 g of 2- Chloro-4,6-dimethoxytriazine (DMT-Cl) in 300 ml of ethyl acetate over 20-30 minutes at ambient temperature for 2-3 hours at 23- 27°C to obtain the DMT active ester of 4-Amino-3-chlorobenzoic acid. The mixture is cooled to 0° to +5°C and 30 0 ml of purified water are added to the solution keeping temperature in the same range. The solution of the deprotected t-leucirae product as the citrate salt is added at 0°C to +5°C over 30-60 minutes, the reaction mixture is then brought to pH 6.5-7. 5 by adding 30% sodium hydroxide (approx. amount: 71 ml), and stirred 6-7 hrs at 20° to 25°C. After completion of the reaction, the phases are separated and the organic layer added to sodium bisulfate solution (15 g of sodium bisulfate in 235 ml of water) and stirred for 3 hrs at 20°C to 25°C. The phases azre separated and the organic layer is washed four times with water (150 ml each), twice with sodium bicarbonate solution (total: 20 g of sodium bicarbonate in 400 ml of water), and once with 1 50 ml of water. To the solution is added 10 g of activated charcoal and 10 g of Dicalite and filtered and the solids washed with 100 ml of ethyl acetate. The filtrate was distilled under vacuum to a volume of 200 ml at < 40°C when the resultant mixture crystallizes. Ethyl acetate (150 ml) was added to a total volume of 350 ml. N- heptane (300 ml) was added over 2 hrs and after stirring the slurry for 3 hrs at 20° to 25°, the solid was filtered, washed with ethyl acetate/N-Heptane (100 ml, 1: 1) and dried at 60°C under vacuum.
