Acetic Acid → HCID 43560304, compound

Participants

Reaction Steps

A solution of 2-bromoaniline (1.720 g, 10.00 mmol), cyclopropanecarbaldehyde (0.374 mL, 5.00 mmol), and acetic acid (2.86 mL, 50.0 mmol) in dichloromethane (50 mL) was heated at 50° C. for 1 hour. The solution was cooled in an ice bath and sodium triacetoxyborohydride (2.119 g, 10.00 mmol) was added. This mixture was stirred for 2 hours while warming to ambient temperature and then partitioned between saturated sodium bicarbonate solution (100 mL) and ethyl acetate (100 mL). The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The residue was purified by flash column chromatography (silica gel, 0-10% ethyl acetate in heptane) to provide the title compound (1.05 g, 93% yield).
