Procedure
A solution of product from step D) (9.43 g; 31 mmol) and triphenylphosphine (10.07 mg; 38 mmol) in toluene (100 ml) was refluxed for 1 hour 30 min. The resulting precipitate was filtered, and washed with ether to give 4-methyloxycarbonyl-3-phenyl-benzyltriphenylphosphonium bromide as a white solid (15.85 g; 90%).
Workup
- filtrationThe resulting precipitate was filtered
- washwashed with ether
