Procedure

To a solution of (4aS,6R,7R,7aR)-6-{4-[(1S)-2,3-dihydro-1H-inden-1-ylamino]-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-2-(4-methoxyphenyl)-7-methylhexahydrocyclopenta[d]-[1,3]dioxin-7-ol (312 mg, 0.594 mmol, as prepared following the procedure in Example 1a-d, using (S)-(+)-1-aminoindan in step c) in THF (1.17 mL) and water (1.17 mL) was added AcOH (3.51 mL, 61.7 mmol) under an atmosphere of nitrogen. The mixture was stirred at rt overnight. The solvent was removed in vacuo and the residue was purified by silica gel chromatography eluting with a gradient of 0 to 10% MeOH in DCM to afford the title compound as a white solid (182 mg, 76%). LC/MS: Rt=0.85 min, ES+ 381 (FA standard).
