Procedure

By the method Example 1, Step K, 0.85 g (0.0033 mole) of 1-(2-fluoro-4-hydroxyphenyl)-1,4-dihydro-4-(3-fluoropropyl)-5H-tetrazol-5-one and 1.21 g (0.0050 mole) of methyl 2-(2-chloromethyl-5-methylphenoxy)propionate (Example 1, Step J) were reacted in the presence of 0.70 g (0.0050 mole) of anhydrous potassium carbonate in 60 mL of N,N-dimethylformamide, yielding 0.42 g of methyl 2-[2-[4-[1,4-dihydro-4-(3-fluoropropyl)-5H-tetrazol-5-on-1-yl]-3-fluorophenoxymethyl]-5-methylphenoxy]propionate as an oil. The NMR spectrum was consistent with the proposed structure. NMR: 1.64 (d, 3H, JHH =8 Hz); 2.2-2.4 (m, 2H); 2,32 (s, 3H); 3.72 (s, 3H); 4.18 (t, 2H, JHH =8 Hz); 4.50-4.64 (dt, 2H, JHH =8 Hz, JHF =45 Hz); 4.84 (q, 1H, JHH =8 Hz), 5.20 (q, 2H, JHH =8 Hz); 6.58-7.40 (m, 6H).
