Diisopropylethylamine → HCID 59606574, compound

300 mg (0.69 mmol) of the compound from Example 37A and 246 mg (2.08 mmol) of N′-hydroxy-3-methoxypropanimidamide were initially charged in 2.6 ml of DMF and reacted with 396 mg (1.0 mmol) of HATU and 0.36 ml (269 mg, 2.1 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: 141 mg (38% of theory)
