Procedure:
Tetrakis(triphenylphosphine)palladium(0) (2.0 mg, 0.002 mmol) and morpholine (5.62 ml, 0.064 mmol) were added to a solution of allyl (R)-3-(tert-butyldisulfanyl)-1-oxo-1-(4-((5S,8S,11S,14S,20S,23S,26S,29S)-5,14,20,29-tetrabenzyl-11-isobutyl-4,10,16,19,23,25,26-heptamethyl-3,6,9,12,15,18,21,24,27,30-decaoxo-1-oxa-4,7,10,13,16,19,22,25,28-nonaazacyclotriacontan-8-yl)butylamino)propan-2-ylcarbamate (Compound 150b) (23.1 mg, 0.016 mmol) in THF (0.16 ml) under a nitrogen atmosphere, and the reaction solution was stirred at 30° C. for 4 hours. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by reverse-phase silica gel column chromatography (0.1% aqueous formic acid solution/0.1% formic acid-acetonitrile solution) to afford the title compound P-150 (10.2 mg, 47%).
