Dichloromethane → N-benzyl-O-benzyl-D-serinamide

참여 물질

반응 단계

To a solution of N-benzyl-O-benzyl-N2-Boc-D-serinamide (30 g) and dichloromethane (150 mL), trifluoroacetic acid (150 mL) was added. The solution was stirred for 2 hours at room temperature for completion of reaction. The solution was concentrated under vacuum to obtain solid which was dissolved in water. The aqueous layer was basified to pH 8-10 with 5% sodium hydroxide. The aqueous layer was extracted with ethyl acetate and the combined organic layers washed with brine solution. Organic layer was concentrated under vacuum to obtain an oily residue solidify by n-Hexane to give 20 g of N-benzyl-O-benzyl-D-serinamide.
