836.5 mg (2.2 mmol) of HATU and 517.0 mg (4 mmol) of N,N-diisopropylethylamine are added to a solution of 760.9 mg (2 mmol) of (3S)-3-{[(benzyloxy)carbonyl]amino}-6-[(tert-butoxycarbonyl)amino]hexanoic acid in 25 ml of anhydrous DMF. After stirring at RT for 45 min 352.5 mg (2.2 mmol) of tert-butyl (2-aminoethyl)carbamate hydrochloride are added. The reaction mixture is stirred at RT for 15 h. The solvent is then evaporated and the residue is taken up in dichloromethane. The organic phase is washed with water, dried over magnesium sulfate and concentrated. The crude product is purified by preparative HPLC.
