実験手順
7-Bromo-5-(2,4-dimethoxybenzoyl)-4-ethyl-4,5-dihydropyrrolo[1,2-a]quinoxaline was prepared from 7-bromo-4-ethyl-4,5-dihydropyrrolo[1,2-a]quinoxaline (see Example 42) and 2,4-dimethoxybenzoyl chloride according to the procedure of Example 106, Step 2. The product was purified via Biotage Horizon® (25S, silica gradient from 5% EtOAc/Hexane to 40% EtOAc/hexane) and isolated as a white foam. MS (ESI) m/z 441/443 ([M+H]+); HRMS: calcd for C22H21BrN2O3, 440.0736; found (ESI+), 441.08006.
