Procedure

A mixture of 0.87 (1.46 mmol) of 9H-fluoren-9-yl-methyl((13S,16R)-13-isopropyl-15-oxo-2,11-dioxa-14-azabicyclo[16.2.2]docosa-1(21),4,18(22),19-tetraen-16-yl)-carbamate and 0.16 g of 10% Pd/C in 100 ml of methanol was stirred under a hydrogen atmosphere at RT. After stirring overnight and addition of 0.5 ml of piperidine, stirring was continued for 2 h, and the mixture was filtered and freed of solvent. The residue was separated by preparative HPLC. The required fractions were combined and freeze dried. 0.18 g of the title compound was obtained as trifluoroacetate.
