L-1-Naphthylalanine Use and Manufacturing
General procedure: Thionyl chloride (11.05 g, 92.92 mmol) was slowly added to a suspension of 1a or 1b (10.00 g, 46.46 mmol) in methanol (100 mL) in an ice bath. The mixture was allowed to warm up to roomtemperature and stirred for 12 h. The solvent was removed under reduced pressure. The obtainedyellow solid was dissolved in ammonia solution (120 mL) and methanol (30 mL), and stirred for 12 h.The mixture was concentrated under reduced pressure. The obtained yellow solid was purified bysilica gel column chromatography using dichloromethane-methanol (12:1) as the eluent, yielding 2a(8.83 g, 83.82%) or 2b (8.10 g, 76.89%) as a white powdery solid.
