Participants

Reaction Steps

Under argon to a solution of trans-3 tert-butoxycarbonylamino-1,2,3,4-tetrahydro-2-naphthalenol (2.02 g) in methylene chloride (40 ml) was added pyridinium dichromate (4.3 g), molecular sieves 3A (6.3 g) and acetic acid (0.76 ml). After 1 hour stirring at room temperature the mixture was poured on a silica gel column (120 g, elution with ethyl acetate: cyclohexane, 1:3) to afford a crude material which was recrystallized from a diethyl ether/cyclohexane mixture to give the title compound (634 mg) as a white solid, m.p. 104°-105° C.
