Reaction Steps

290 mg (0.390 mmol) of benzyl((1S,8S)-8-[(tert-butoxycarbonyl)amino]-1-{3-[(tert-butoxycarbonyl)amino]propyl}-17,17-dimethyl-2,10,15-trioxo-16-oxa-3,11,14-triazaoctadec-1-yl)carbamate (Example 226A) are dissolved in 10 ml of a 4/1 glacial acetic acid/water mixture. 75 mg of palladium on activated carbon (10%) are added thereto, and the mixture is then hydrogenated under atmospheric pressure for 15 h. The reaction mixture is filtered through a Millipore filter and the filtrate is concentrated and dried under high vacuum. The crude product is reacted without further purification.
