2-bromoprop-2-enoxymethylbenzene

Conditions: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Dichloro-[dicyclohexyl(phenyl)phosphaniumyl]-tritert-butylphosphaniumyl-palladium (981 mg, 0.150 mmol) and 2-bromoallyloxymethylbenzene (341 mg, 1.50 mmol) were dissolved in DMF (1 mL). A solution of benzyl 3-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (1.11 g, 3.00 mmol) in DMF (3 mL) was added the mixture was heated at 90° C. for 3 h. The mixture was then filtered through Celite using ethyl acetate. The filtrate was then washed with brine, dried over sodium sulfate, filtered, and concentrated. The residue from step 1 was taken up in isopropanol (2 mL) and was added to 10% Pd/C (160 mg, 0.150 mmol). The vessel was purged with nitrogen and a balloon of hydrogen was added and the reaction mixture was allowed to stir overnight. The reaction mixture was filtered through Celite and the filtrate was concentrated. The residue was partitioned between aqueous 2M Na2CO3 and ethyl acetate. The layers were separated and the organic phase was discarded. To the aqueous phase was added 1M HCl until the solution was pH 3. The solution was then extracted with EtOAc (3×) and the combined organic layers were dried over sodium sulfate, filtered, and concentrated to provide 4-(1-hydroxypropan-2-yl)-3-methoxybenzoic acid. ESI-MS m/z calc 210.1, found 211.1 (M+1)+. Retention time: 1.19 minutes (3 min run). The mixture was then filtered through Celite The filtrate was then washed with brine dried over sodium sulfate filtered concentrated The vessel was purged with nitrogen a balloon of hydrogen was added The reaction mixture was filtered through Celite the filtrate was concentrated The residue was partitioned between aqueous 2M Na2CO3 and ethyl acetate The layers were separated To the aqueous phase was added 1M HCl until the solution The solution was then extracted with EtOAc (3×) the combined organic layers were dried over sodium sulfate filtered concentrated
