Versuchsvorschrift

Starting material 37 (60 mg, 0.2 mmol, 70% content) and 6-Amino-3H-benzooxazol-2-one (30, 25 mg, 0.2 mmol) were dissolved in 2 ml DMF. Then EDCl (38 mg, 0.2 mmol) and HOBt (31 mg, 0.2 mmol) were added. The reaction was stirred over night at ambient temperature, concentrated in vacuo and purified by prep HPLC (Method 1). By concentration of the pure fractions the desired product 38 (23 mg, 0.04 mmol, 24%) could be isolated.

Aufarbeitung

  1. concentrationconcentrated in vacuo
  2. custompurified by prep HPLC (Method 1)
