Reaction Steps

To a solution of (R)-α-azido-10,11-dihydro-5H-dibenzo[a,d]cycloheptene-5-acetic acid (3.5 g, 1.9 mmol) in tetrahydrofuran (75 mL), water (10 mL), and concentrated hydrochloric acid (1 mL) is added palladium on carbon (0.5 g, 20%). The mixture is shaken under 52 pounds per square inch (psi) of hydrogen at 25° C. for 6 hours. Solid is filtered. The filtrate is concentrated in vacuo to give a light green solid, which is recrystallized in 3N hydrochloric acid (with activated charcoal) to give the title compound as a white solid, 2.84 g; mp 313°-314° C. (dec), [α]D =-47.6° (c=1.0, methanol).
