Reaktionsschritte

The mixture of 5 eq. phosphorous acid, 4-aminobutyric acid and morpholine. HCl is melted together until uniform solution is formed. The reaction mixture is cooled to about 70° C. and 2 eq. of PCl3 are carefully added. The mixture is heated for about 5.5 hours before the reaction mixture is hydrolyzed in aqueous acid at about 80° C. and alendronate is isolated from an ethanolic solution.
