実験手順
3 ml of trifluoroacetic acid is added to 200 mg of ester 6-2 in 10 ml of dichloromethane, agitation is carried out for 2 hours at ambient temperature then 10 ml of toluene is added. After evaporating under reduced pressure, taking up in dichloromethane and crystallizing by adding an Et2O/pentane mixture, 175 mg of 6-3 is obtained.
