Procedure

Followed the coupling procedure similar to that described in Compound VIII-2 (Example 65), where the starting materials were ethyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)cyclohex-3-enecarboxylate and 2-chloro-6-methoxy-3-(trifluoromethyl)quinoxaline (Intermediate 11) and where the reaction here was stirred under N2 atmosphere at 100° C. for 3 hours. Ethyl 4-(6-methoxy-3-(trifluoromethyl)quinoxalin-2-yl)cyclohex-3-enecarboxylate was isolated (800 mg, yield 55%) as yellow solid.
