N-Fmoc-N'-Boc-L-2,3-Diaminopropionic acid Use and Manufacturing
To a (25)-3-amino-2-[{9H-fluoren-9yl-methanol}amino]propanoic acid as hydrochloride salt (15 g, 41.3 mmoles) in a 1: 1 mixture of water (150 mL) and tetrahydrofuran (150 ml) was added solid sodium bicarbonate (6.95g, 82.7 mmol) at 0°C under stirring. Boc anhydride (10.82 g, 49.6 mmol) was added drop-wise to it. The reaction mixture was allowed to warm to room temperature and stirred for 16 hours. The reaction mixture was extracted with 250 ml of diethyl ether. The aqueous layer was acidified to pH of 1 by addition of 5percent potassium hydrogen sulphate solution followed by extraction with 2 x 250 ml ethyl acetate and 250 ml dichloromethane. The combined extracts were dried over anhydrous sodium sulphate and the solvent evaporated under reduced pressure to obtain the 13.08 g of titled product, as a white solid in 67percent yield. Analysis:Mass: 427.3 (M+1); for Molecular Formula of C23H26N206 and for Molecular Weight of 426.
