Procedure
The title compound was prepared by a method analogous to that described for Intermediate (6) using 4-trifluoromethyl-1H-pyrazole and 2-chloro-3-methyl-5-nitro-pyridine. 1H NMR (400 MHz, CDCl3, δ): 8.21 (s, 1H), 7.85 (s, 1H), 7.75 (d, J=2.4 Hz, 1H), 6.93 (d, J=2.4 Hz, 1H), 3.85 (s, 2H), 2.32 (s, 3H).
