DL-2,3-DIAMINOPROPIONIC ACID MONOHYDROCHLORIDE Use and Manufacturing
To a solution of 2, 3-diaminopropionic acid hydrochloride (3.52 g 25 mmol) in ethanol (50 mL), K2CO3 (1.73 g, 12.5 mmol) was added. The resulting suspension was refluxed for30 min, and then a solution of ortho-vanillin (7.61, g 50 mmol) in ethanol (50 mL) was added to the reaction mixture. The reaction mixture was then refluxed for1 h, cooled, and filtered. The solvent was removed, and the residue was crystallized from ethyl acetate.Yield 6.08 g (16.3 mmol, 65%), yellow powder. IR spectrum, nu, cm-1: 3422, 1645, 1630, 1603. 1 NMRspectrum (DMSO-d6), delta, ppm: 3.74 s (3, OCH3), 3.75s (3, OCH3), 4.02 d. d (1, NCH2CHCO2H, 3JHH =12.7, 7.4 Hz), 4.12 d. d (1, NCH2CHCO2H, 3JHH =12.9, 4.1 Hz), 4.29 d. d (1, NCH2CHCO2H, 3JHH =7.4, 4.0 Hz), 6.70 t (2Ar, 3JHH = 7.9 Hz), 6.75 t (2Ar, 3JHH = 7.9 Hz), 6.97 q (2Ar, 3JHH = 7.9 Hz), 8.48 s(1, N=CH), 8.53 s (1, N=CH), 13.73 br. s (2, OH). Mass spectrum (HRMS-ESI+), m/z: 373.1388[M + H]+ (calculated for C19H21N2O6: 373.1394).
Dl-2,3-Diaminopropionic Acid, Hydrochloride can be used for pharmaceutical composition for viral infections.
