Allyl bromide → 5-(Allyloxy)-1,3-benzodioxole-4-carbaldehyde

Participants

Reaction Steps

To a stirred solution of 5-hydroxy-1,3-benzodioxole-4-carbaldehyde (0.166 g, 1.00 mmol) and K2CO3 (1.00 mmol) in dry N,N-dimethylformamide (2 ml) was added allylbromide (1.00 mmol) under argon. The mixture was stirred at room temperature for 18 h until the starting material was consumed (monitored by TLC). Then the mixture was poured onto ice-water (15 ml). The aqueous phase was filtered off, the precipitated product was washed with water and n-heptane and dried to give analytically pure crystals.
