106 g (1.05 mol) N-methyl-N-pentylamine was added to cooled methanol of a temperature of 0–5° C. 108 g (1.25 mol) methyl acrylate was added to the solution and the mixture was stirred at room temperature for 8 hours. Then methanol was distilled off in vacuo and the residue was purified by distillation to obtain 188.6 g N-methyl-N-pentyl-β-alanine methyl ester (96.1%)
