Methyl 4-nitro-L-phenylalaninate hydrochloride Use and Manufacturing

Thionyl chloride (1.03 ml, 14.2 mmol) was added dropwise to a suspension of L-p- Nitrophenylalanine (0.995 g, 4.73 mmol) in 10 ml of MeOH at 0°C. After the addition, the solution formed was allowed to warm to room temperature. The reaction mixture was heated under reflux overnight and then concentrated. The crude material was recrystallized from methanol/ethyl acetate to give 1.012 g (95percent) of L-p-Nitrophenylalanine Methyl Ester Hydrochloride.SOCl(2) The above product was dissolved in 20 mL of saturated anhydrous methanol and hydrogenated for 15 min, and refluxed at room temperature for 4 h.The solid was collected by dryness to give 8.5 g of methyl 2-amino-3-methyl-4-amino-3-(4-nitrophenyl)chloropropionate (methyl 2-amino-3-methyl).(4-nitrophenyl)propanoate hydrochloride).
