実験手順

9.3 g (26.3 mmol) of 3-(3-phenylpropylamino)-1-hydroxypropane-1,1-diphosphonic acid are refluxed for 36 hours with 6.1 ml of formic acid and 4.2 ml of a 38% formaldehyde solution in water. The reaction solution is concentrated by evaporation under reduced pressure and the residue is diluted with acetone, yielding 3-[N-(3-phenylpropyl)-N-methyl-amino]-1-hydroxy-propane-1,1-diphosphonic acid in the form of colourless crystals of m.p. 219° (decomp.).
