실험 절차

The methyl ester of the title compound, {(S)-6-[(R)-4-(6,7-dihydro-pyrazolo[1,5-a]pyrazin-5-ylmethyl)-5-trifluoromethyl-indan-1-yloxy]-2,3-dihydro-benzofuran-3-yl}-acetic acid methyl ester, is prepared from {(S)-6-[(R)-4-bromomethyl-5-trifluoromethyl-indan-1-yloxy]-2,3-dihydro-benzofuran-3-yl}-acetic acid methyl ester and 4,5,6,7-tetrahydro-pyrazolo[1,5-a]pyrazine following a procedure analogous to that described for Intermediate 42. The crude product is directly submitted to the saponification conditions described for Example 1 to give the title compound upon chromatography on reversed phase (HPLC; acetonitrile/water). LC (method 6): tR=1.07 min; Mass spectrum (ESI+): m/z=514 [M+H]+.
