Reaction Steps
To the solution of 2,3-dihydrobenzofuran (0.05 mol) dissolved in dichloromethane (30 mL), AlCl3 (0.10 mol) is added batch by batch and 3-chloropropionyl chloride (0.055 mol) is added dropwise, while the internal temperature is maintained below 5° C. Following procedures described in General Method One-Method A, 3-chloro-1-(2,3-dihydrobenzofuran-5-yl)-acetone is obtained as a white solid (8.4 g). The yield is 80.2%. MS(m/z): 211.0 [M+1]+.
