YieldReaction ConditionsOperation in experiment
94% With calcium hydroxide; In water; acetone; at 25 - 30℃; for 3h;pH 9;Green chemistry; In a mixture of 50 ml water and acetone (ratio 2:1 by weight) 10 g tert-Leucine, 8 g sodium carbonate and 20 g Boc anhydride are charged. The mixture is stirred at room temperature, e.g. of about 25 to about 30°C, until the conversion is >ggpercent (takes about 3 hours). The pH is kept above 9, and, if needed, sodium carbonate is added. The acetone is removed by vacuum distillation, and the distillate can be reused in a subsequent batch. The remainder is extracted with 5 ml toluene. The organic phase is distilled, and the toluene fraction can be reused in the subsequent batch. The inorganic phase is acidified to pH 2 to 4 by addition of hydrochloric acid, and 0.1 g of seed crystals are added. The precipitated product is isolated by filtration, washed with water and dried at 40°C under vacuum. Yield is 16.8 g, equal to 94percent N-Boc-tert-Leucine. HPLC analysis shows a purity of 99.89 area-percent.
