Reaction Steps

{4-[5-(4-trifluoromethyl-phenyl)-isoxazol-3-ylmethylsulfanyl]-5,6,7,8-tetrahydro-naphthalen-1-yloxy}-acetic acid methyl ester (compound 102A) The title compound was prepared in the manner analogous to Example 1F using (4-mercapto-5,6,7,8-tetrahydro-naphthalen-1-yloxy)-acetic acid methyl ester and the product from Example 42C; recrystallization from methanol afforded the title compound. MS m/z 478 (M+1). Step 2. {4-[5-(4-trifluoromethyl-phenyl)-isoxazol-3-ylmethylsulfanyl]-5,6,7,8-tetrahydro-naphthalen-1-yloxy}-acetic acid (compound 102) The title compound was prepared in the manner analogous to Example 1 using the product from Example 102A. mp 167-170° C.; 400 MHz 1H NMR (DMSO-d6) δ 8.01 (d, 2H, J=8 Hz), 7.83 (d, 2H, J=8.3 Hz), 7.14 (d, 2H, J=8.5 Hz), 7.07 (s, 1H), 6.58 (d, 2H, J=8.8 Hz), 4.56 (s, 2H), 4.07 (s, 2H), 2.64 (m, 2H), 2.53 (m, 2H), 1.60 (m, 4H); MS m/z 464 (M+1). The compounds of the present invention can also be prepared using combinatorial chemistry methods. In particular, compounds of Examples 103-134 were prepared using combinatorial chemistry analogous to that previously described in Examples 1-102. The combinatorial chemistry methods useful in the present invention include those where an activated alcohol is contacted with a thiol followed by saponification of the resulting ester to afford the desired products. Such methods can be illustrated by previously described Scheme 1 where compound D is an exemplary thiol, compound Y is an exemplary activated alcohol, and compound F is an exemplary desired product.
