To a solution of 5-cyclopropyl-2-(3-(piperidin-4-ylidenemethyl)phenoxy)pyridine trifluoroacetate (125 mg, 0.408 mmol) in DMSO (5 mL) was added phenyl pyridin-3-ylcarbamate (87.4 mg, 0.408 mmol) followed by triethylamine (0.12 mL, 0.82 mmol). The reaction was heated to 60° C. overnight and then allowed to cool to RT. The reaction mixture was partitioned between EtOAc and water. The organic layer was dried and concentrated. Purification by silica gel column chromatography (0-5% MeOH/CH2Cl2) afforded the title compound as a white foam (101 mg, 58% yield).
