実験手順
To a solution of 500 mg (1.20 mmol) of the carboxylic acid from Example 9A in 15.0 ml of DMF were added, at RT, 545 mg (1.43 mmol) of HATU and 0.46 ml (2.63 mmol) of N,N′-diisopropylethylamine, and the mixture was stirred for 30 min. Subsequently, the mixture was admixed with 565 mg (3.56 mmol; 75% purity) of isopropyl N′-hydroxyimidocarbamate [G. Zinner, G. Nebel, Arch. Pharm. 1970, 303, 385-390] and then stirred at RT for 2 h and at 120° C. for 2 h. The reaction solution was concentrated under reduced pressure and purified directly by means of preparative HPLC. Yield: 344 mg (58% of theory)
