실험 절차

4-(2-Tetrahydro-3H-pyranoxy)phenylmagnesium bromide (110 mL, 0.5 M in THF, 55 mmol) was added dropwise to a solution of 1-methyl-1H-imidazole-5-carbaldehyde (4.7 g, 50 mmol) in THF (790 mL) at −78° C. After stirring −78° C. for 2 hours, the reaction was quenched with saturated NH4Cl (aq) and warmed to room temperature. The mixture was extracted with EtOAc (500 mL), and the organic phase was washed with water and brine, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to give 14 g of the crude product 74.1, which was used in the next reaction without further purification.
