Procedure

Title compound was prepared by a method analogous to that described for Intermediate 7, replacing 3,4-difluoro-2-pyridinecarbaldehyde with 3,5-difluoro-4-pyridinecarbaldehyde (FRONTIER) and using MeOH as solvent. (200 mg, 1.398 mmol, 73% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm: 8.51 (s, 2H), 5.55 (t, 1H), 4.55-4.57 (m, 2H). [ES+MS] m/z 146 (MH+).
