Reaction Steps

To an ice cooled solution of methyl 3-butenoate (2.0 g, 20 mmol) in THF (20 ml) 9-borabicyclo(3,3,1)nonane (49 ml, 0.5M in tetrahydrofurane) was added within 1 hour. After additional stirring for 4.5 hours potassium carbonate (7.5 g, 54 mmol), 2-bromobenzyl alcohol (3.4 g, 18.2 mmol), dimethylformamide (60 ml) and palladium (dppf)-dichloride (0.665 g, 0.91 mmol) were added and the mixture was stirred at 60° C. overnight. After cooling the mixture was filtered over Celite and evaporated. The residue was purified by column chromatography (eluent hexane/ethyl acetate: 4:1 gradually to 1:1) to yield 2.46 g (65%) of product.
