Reaction Steps

To a solution of 2 (100 mg, 0.589 mmol) in THF (6 mL) at −78° C., was added n-BuLi (2.5 M in hexane, 0.259 mL, 8,84 mmol) and the reaction mixture was stirred 15 minutes. 2-Furoyl chloride (0.087 mL, 0.884 mmol) was added drop wise; the mixture was stirred for additional 2 hours and partitioned between DCM and water. The organic layer was separated, dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford title compound 239 (35 mg, 23% yield, crude) as a yellow solid, that was used in the next step without additional purification. MS (m/z): 264.0 (100%), 266.0 (40%) (M+1).
