Procedure

The title compound was prepared in analogy to Example 1, from 2,5-dichloro-4-[3-(4-cyclopropyl-3,4-dihydro-2H-quinoxaline-1-carbonyl)-pyridin-4-yloxy]-benzoic acid (Example 29, intermediate) and 2-amino-ethanol (commercially available, CAS RN 141-43-5). The product was purified on a preparative HPLC system (Phenomenex Gemini column) using a gradient of acetonitrile:water (containing 0.05% formic acid) (10:90 to 98:2) to give the desired compound as a light brown foam (60%). MS (ESI): m/z=527.124 [M+H]+.
