Procedure
A solution of crude ketone from Step 1 in acetone (250 mL) and HCl 10% (25 mL) was stirred for 6 hours, diluted with Et2O, washed with a saturated NH4Cl solution, H2O (3×), brine and dried (MgSO4). After evaporation of the solvent, the residue was saturated with hexane and filtered to afford the title compound as pale yellow solid.
