Reaction Steps

A mixture of the dibenzylamine 20-6 (0.22 g, 0.44 mmol) in EtOH/H2O/AcOH (26 mL/3 mL/1.0 mL) was degassed with argon and treated with Pd(OH)2 (100 mg). The mixture was placed under 1 atm of H2. After stirring for 18 h, the mixture was diluted with EtOAc and filtered through celite. The filtrate was concentrated and the residue purified by flash chromatography (20% 20:1:1 EtOH/NH4OH/H2O—80% EtOAc) to give the tert-butyl ester 20-7 as a white solid.
