Reaction Steps

To the solution of 1,2-methylenedioxybenzene (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-(1,2-methylenedioxybenzen-4-yl)-propanone is obtained as a white solid (9.5 g). The yield is 90.0%. MS(m/z): 213.0 [M+1]+.
