Reaction Steps

A solution of this material in dichloromethane was treated with trimethylsilyl bromide as described in Example 24 to give, after ion-exchange chromatography, 1-fluoro-3-methoxy-3(1,2,4-triazol-3-yl) propane phosphonic acid (Compound No. 46 in Table 1) also as a mixture of diastereoisomers in a ratio of 3:1 or 1:3. NMR(D2O): δ2.15-2.4(2H,m); 3.25(3H,s); 4.4-4.8(1H,m); 4.85(1H,t); 8.9(1H,2xs). FAB M/S: MH+ 240. More vigorous deprotection, for example in the presence of iodide ion, will result in ether cleavage to give 1-fluoro-3-hydroxy-3(1,2,4-triazol-3-yl)propane phosphonic acid (Compound No. 45 in Table 1), also as a mixture of diastereoisomers.
