実験手順

A solution of acid 53 (1.9 g, 6.53 mmol) in methanol (20 mL) was added concentrated sulfuric acid (2 mL) and the reaction mixture was stirred at 60° C. for 4 h. The organic layer was separated, dried over Na2SO4, filtered and concentrated to afford methyl 2-(4-bromophenyl)-2-phenylacetate 54 (1.7 g, 85% yield) as a brown oil.
