To a solution of (1-(4-methoxy-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-1,2,4-triazol-3-yl)methanol (70 mg, 0.285 mmol) in THF (5 mL) was added ethylmagnesium bromide (1.284 mL, 1.284 mmol) at −40° C. After stirring at −5° C. for 1H, pyridine (0.012 mL, 0.143 mmol) was added quickly. The mixture was cooled to −40° C. and ethyl 2-chloro-2-oxoacetate (0.130 mL, 1.142 mmol) was added. After stirring at −40° C. for 30 min, the reaction mixture was quenched by adding i-PrOH and water. The mixture was extracted with EtOAc (2×40 mL). The organic layers were combined, washed with brine (30 mL), dried over MgSO4 and concentrated under vacuum to give crude product ethyl 2-(7-(3-(hydroxymethyl)-1H-1,2,4-triazol-1-yl)-4-methoxy-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetate (70 mg, 0.203 mmol, 71.0% yield). LCMS: m/z 346.1 (M+H)+, 1.42 min (method 8).
