Procedure

68.8 g (367.4 mmol) N-methyl-N-pentyl-β-alanine methyl ester was hydrolyzed by refluxing with 138 ml water. Water was distilled off and 300 ml diethyl carbonate were added, followed by azeotropic distillation of diethyl carbonate/water (30 ml) to remove residual water. About 290 ml of a diethyl carbonate solution containing 63 g N-methyl-N-pentyl-β-alanine was obtained which could directly be used for the subsequent bisphosphorylation step.
