Triphenylphosphine → HCID 68420767, compound

Participants

Reaction Steps

Triphenylphosphine (0.22 g, 0.84 mmol) and palladium (II) acetate (47 mg, 0.21 mmol) were dissolved in tetrahydrofuran (2.0 mL) in an atmosphere of argon, followed by stirring at room temperature for 10 minutes. To the reaction mixture was added a solution of methyl 3,5-dimethoxy-2-(4-methoxybenzoyl)phenylacetate (0.78 g, 2.1 mmol) obtained in Example 26, Step 1 in formic acid (20 mL), followed by stirring at 80° C. for 5 hours. The reaction mixture was cooled to room temperature and then concentrated. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane=1/4-1/1) to obtain Compound 27 (0.39 g, 56%).
