Potassium Carbonate → HCID 50905028, compound

Participants

Reaction Steps

Following the same procedure as in Example 2, 3.65 g (0.02 moles) of 5-hydroxy-6-propyl-benzo[1.3]dioxole were reacted with 2.7 g (0.02 moles) of 1-bromo-2-butyne and 2.8 g (0.02 moles) of anhydrous potassium carbonate in 15 ml of acetone. After the work up of the reaction as in Example 2, a residue was obtained that after distillation at 115-117° C./0.2 mbar gave 3.9 g of a liquid product that, after some time, crystallized with m.p. 39° -40 ° C. and whose NMR and MS analyses correspond to those of the aforementioned compound.
