실험 절차

A solution of the compound obtained in Step A (3 g-5.5 mmol) in 100 ml of dichloromethane and 15 ml of TFA is stirred for 6 hours under argon. The solvents are distilled off in vacuo. The residue is triturated in diisopropyl ether, filtered off with suction and then dried in vacuo to yield the expected product in the form of white crystals.
