Reaction Steps

A dried 25 ml of two-neck round bottom flask was filled with argon gas and the solution of (2-chloro-5-ethynyl-4-methanesulfonylamino-benzyl)-carbamic acid t-butyl ester (182.6 mg, 0.51 mmol) in methylenechloride was put into the flask. To the solution were added 5-6 drops of CF3COOH and stirred for 12 hours. After confirming the completion of the reaction with TLC, the resulting solution was concentrated under reduced pressure using toluene to yield brown syrup (98.1 mg, 114.23%).
