Procedure
step b To a solution of 120 (4.29 g, 18.40 mmol) in MeOH (50 mL) and toluene (75 mL) was added dropwise trimethylsilyldiazomethane (15.64 mL, 31.3 mmol) until the yellow color persisted. The resulting solution was stirred for 30 min then the reaction was quenched with several drops of HOAc until the yellow color disappeared. The solvents were evaporated to afford methyl 4-(2,2,2-trifluoro-acetylamino)-benzoate (122) which was used in the next reaction without further purification.
