Procedure

Under argon to a solution of 3-tert butoxycarbonylaminodecahydro-2-naphthalenol (0.27 g) in methylene chloride (5 ml was added pyridinium dichromate (572 mg), molecular sieves 3A powder (791 mg) and acetic acid (100 μl ). The reaction mixture was stirred for 50 minutes at room temperature. The black mixture was filtered through a silica gel column (60 g, elution with ethyl acetate:cyclohexane, 1:4) to give, after evaporation of solvents, the title compound as a viscous oil (165 mg).
