Reactant 4
Product 1
Procedure
The methyl ester of the title compound is prepared from {(S)-6-[(R)-4-(2-bromo-pyridin-3-yl)-7-fluoro-indan-1-yloxy]-2,3-dihydro-benzofuran-3-yl}-acetic acid methyl ester and 1,3,5-trimethyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrazole following a procedure analogous to that described in Step 5 of Intermediate 1. Saponification of the methyl ester, {(S)-6-[(R)-7-fluoro-4-[2-(1,3,5-trimethyl-1H-pyrazol-4-yl)-pyridin-3-yl]-indan-1-yloxy]-2,3-dihydro-benzofuran-3-yl}-acetic acid methyl ester, following a procedure analogous to that described for Example 4 gives the title compound; if the title compound does not precipitate from the aqueous solution, the crude title compound is purified by HPLC. LC (method 9): tR=0.88 min; Mass spectrum (ESI+): m/z=514 [M+H]+.
