Ammonium Chloride → HCID 66777421, compound

Participants

Reaction Steps

To a solution (20 mL) of 5-chloro-3-methyl-1-benzofuran-2-carbaldehyde (1.00 g) synthesized in Example A88(2) in tetrahydrofuran was added a 1.0M solution (10.3 mL) of isobutylmagnesium bromide in tetrahydrofuran at 0° C., and the mixture was stirred for 1 hr. Saturated aqueous ammonium chloride solution was added to quench the reaction, and the reaction mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (20% ethyl acetate/hexane) to give the title object compound (650 mg, 50%) as a colorless oil.
