Reaction Steps
The procedure of Example 9 is repeated, starting from tetraethyl 2-(pyrazol-1-yl)ethane-1,1-diphosphonate and tetraethyl 2-(imidazol-1-yl)ethane-1,1-diphosphonate. Treatment with trimethylbromosilane and working up with aqueous methanol gives 2-(pyrazol-1-yl)ethane-1,1-diphosphonic acid, m.p. 227° C. (dec.), and 2-(imidazol-1-yl)ethane-1,1-diphosphonic acid, m.p. 255° C. (dec.).
