Reaction Steps
The title compound was prepared in analogy to Example 77, from 4-(2,5-dichloro-phenoxy)-pyrimidine-5-carboxylic acid (Example 76, intermediate a) and 1,2,3,4-tetrahydroquinoxaline (commercially available, CAS RN 3476-89-9). The compound was purified by preparative HPLC (Phenomenex Gemini column) using a gradient of acetonitrile:water (10:90 to 98:2) to give 16 mg (20%) of the desired compound. MS (ESI): m/z=401.0 [M+H]+.
