Procedure

N-[(1S,2S)-6-ethoxy-2,3-dihydro-1-hydroxy-1H-inden-2-yl]-2-(hydroxymethyl)benzamide and N-[(1R,2S)-6-ethoxy-2,3-dihydro-1-hydroxy-1H-inden-2-yl]-2-(hydroxymethyl)benzamnide (XVII, Example 16, 200 mg, 0.61 mmol) is dissolved in acetic acid (2.5 mL). The reaction mixture is stirred for 18 hr at 80°. Then the mixture is partitioned between methylene chloride and water. The aqueous phase is separated and adjusted to pH=10 using aqueous ammonium. The product is extracted with methylene chloride. The organic layers are concentrated to give the same title compound (VII) as EXAMPLE 6 and its cis-diastereomer.
