실험 절차

200 mg (0.48 mmol) of the compound from Example 39A and 96 mg (0.96 mmol) of N′-hydroxycyclopropanecarboximidamide were initially charged in 1.8 ml of DMF and reacted with 274 mg (0.72 mmol) of HATU and 0.25 ml (186 mg, 1.44 mmol) of N,N-diisopropylethylamine. The reaction mixture was stirred at RT for 15 minutes and then partitioned between water and ethyl acetate. The organic phase was washed repeatedly with water, dried over sodium sulphate and concentrated under reduced pressure. The residue was dissolved in 2.0 ml of DMF and converted in a microwave at 180° C. for 2 minutes. The reaction mixture was purified by means of preparative HPLC. Yield: 25 mg (10% of theory)
