Reaction Steps
A solution of (3R,6S,9S,12S,15S,18S,21R,24S,27S,30S,33S)-6-[(1R)-1-hydroxyethyl]-9-[(1R,2R,4E)-1-hydroxy-2-methylhex-4-en-1-yl]-15,18,27,30-tetraisobutyl-12-isopropyl-33-(1-methoxyethyl)-1,3,4,10,13,19,21,24,28-nonamethyl-1,4,7,10,13,16,19,22,25,28,31-undecaazacyclotritriacontane-2,5,8,11,14,17,20,23,26,29,32-undecone (60 mg) in MeOH (6.0 ml) was hydrogenated over 20% Pd/C (50% wet; 30 mg) at room temperature for 2 hrs. The mixture was filtered and the filtrate was concentrated. The residue was evaporated to give (3R,6S,9S,12S,15S,18S,21R,24S,27S,30S,33S)-6-[(1R)-1-hydroxyethyl]-9-[(1R,2R)-1-hydroxy-2-methylhexyl]-15,18,27,30-tetraisobutyl-12-isopropyl-33-(1-methoxyethyl)-1,3,4,10,13,19,21,24,28-nonamethyl-1,4,7,10,13,16,19,22,25,28,31-undecaazacyclotritriacontane-2,5,8,11,14,17,20,23,26,29,32-undecone (56 mg).
