Reaction Steps

(R)-2-(9-Chloro-7-(4-isopropoxy-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetic acid (15 mg) was dissolved in THF (0.5 mL) and aqueous ethylenediamine (16 uL, 2.27 M) was added. The homogeneous solution was left to stir at room temperature for 2d. ACN (300 μL) was then added and the reaction was stirred at room temperature for one additional day. The reaction mixture was evaporated to dryness and 0.5 mL of EtOAc was added. After stiffing for 24 h at room temperature, a solid had formed which was collected by filtration. The PXRD pattern of the title compound is shown in FIG. 10; and the DSC and TGA are shown in FIG. 11.
