Procedure
A solution of compound 189 (0.673 g, 1.08 mmol) in a 1M solution of tetrabutylammonium fluoride in THF (1.5 mL, 1.5 mmol) was stirred for 90 min at room temperature. The reaction mixture was diluted with AcOEt, washed with 5% KHSO4, water, dried over MgSO4, filtered and concentrated to give a solid material which was triturated with DCM, to afford title compound 190 (0.805 g, 75% yield). The supernatant was collected, evaporated and the residue was purified by flash column chromatography (eluent: 50% AcOEt in DCM) to afford additional amount of 190 (0.161 g, 15% yield).
