実験手順

362.8 mg (0.954 mmol) of HATU and 123.3 mg (0.954 mmol) of N,N-diisopropylethylamine are added to a solution of 207.5 mg (0.867 mmol) of N-[(benzyloxy)carbonyl]-L-serine in 10 ml of anhydrous DMF. After stirring at RT for 15 min, 165 mg (0.867 mmol) of tert-butyl(3-amino-2-hydroxypropyl)carbamate 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.
