Procedure

Using the Schotten-Bauman method of acylation, N-methacryloylalanine was prepared. Coupling of MA-Ala-OH (5.35 g; 0.034 mol) with HCl.Val-Ala-OMe (8.1 g) was performed in dimethylformamide by means of dicyclohexylcarbodiimide (7.0 g) in the presence of triethylamine (3.4 g). Recrystalization from CH2Cl2 /pentene gave 9.5 g of MA-Ala-Val-Ala-OMe.
