実験手順
A solution of p-nitro-L-phenylalanine (12.6 g) and c.HCl (7.5 g) in methanol (150 ml) was refluxed for 1.5 hours and the solvent then evaporated in vacuo. The residue was triturated with ether and recrystallised from SVM to give the desired product as a off-white solid, [α]25 +15.3° (c=0.55, MeOH).
