A mixture of 5-hydroxy-2-methoxybenzaldehyde (395 mg, 2.58 mmol, 1 eq.), 3-(chloromethyl)-2-(1-isopropyl-1H-pyrazol-5-yl)pyridine hydrochloride (700 mg, 2.58 mmol, 1 eq.), and K2CO3 (1.4 g, 10.32 mmol, 4 eq.) in DMF (10.0 mL) was heated at 70° C. for 2 h. The mixture was cooled, filtered, concentrated, and purified on silica gel using a mixture of EtOAc and hexanes as eluent to give 5-((2-(1-isopropyl-1H-pyrazol-5-yl)pyridin-3-yl)methoxy)-2-methoxybenzaldehyde (590 mg, 65%) as an off-white solid.
