6-Bromo-3-benzofuranacetonitrile → HCID 57192363, compound

Participants

Reaction Steps

A solution of 11-6 (10.9 g, 0.0462 mol) in THF (100 mL) was cooled to 0° C. and treated dropwise with BH3 /THF solution (1Molar, 110.8 mL, 0.11 mol). The cold bath was removed and the reaction stirred overnight. MeOH was carefully added (20 mL) and the solvent removed under vacuum. The residue was dissolved in 50 mL MeOH and 400 mL MeOH saturated with HCl and heated to reflux for 3 hours. The volatile components were removed under vacuum and the residue was suspended in Et2O. A bright yellow solid percipitated and was collected and washed five times with Et2O, then dried under vacuum to give 11-7 as a tan solid.
