Participants

Reaction Steps

By the method of Example 1, Step K, 0.49 g (0.0016 mole) of 3-chloro-2-(2-fluoro-4-hydroxyphenyl)-4,5,6,7-tetrahydroindazole and 0.52 g (0.002 mole) of methyl 2-(2-chloromethyl-5-chlorophenoxy)propionate (Example 2, Step F) were reacted in the presence of 0.41 g (0.003 mole) of anhydrous potassium carbonate in 30 mL of N,N-dimethylformamide, yielding 0.64 g of methyl 2-[2-[4-(3-chloro-4,5,6,7-tetrahydroindazol-2-yl)-3-fluorophenoxymethyl]-5-chlorophenoxy]propionate as a syrup. The NMR and IR spectra were consistent with the proposed structure. NMR: 1.64 (d, 3H, JHH =8.0 Hz); 1.82 (m, 4H); 2.50 (t, 2H, JHH =4.0 Hz); 2.68 (t, 2H, JHH =4.0 Hz); 3.76 (s, 3H); 4.82 (q, 1H, JHH =8 Hz); 5.18 (s, 2H,); 6.78-7.40 (m, 6H).
