1-(5-Chlorobenzo[d][1,3]dioxol-7-yl)ethanol → 1-(6-Chloro-1,3-benzodioxol-4-yl)ethanone

Participants

Reaction Steps

1-(5-Chlorobenzo[d][1,3]dioxol-7-yl)ethanol (155 mg, 0.77 mmol) was dissolved in 6 mL of dichloromethane. PCC (416 mg, 1.93 mmol) was added portionwise and the mixture was stirred for 16 h (reaction is likely to be completed earlier). The mixture was filtered through a plug of celite. The solvent was removed by rotary evaporation to collect the desired product (90 mg, 59% yield). 1H NMR (400 MHz, CDCl3): δ 7.36 (d, 1H), 6.96 (d, 1H), 6.14 (s, 2H), 2.59 (s, 3H).
