Procedimiento

A solution of 1a (0.80 g, 2.06 mmole) in 40% trifluoroacetic acid/dichloromethane (15 mL) was stirred at room temperature for 4 h. The solvent was removed by rotary evaporation, and the resulting organic residue was carefully partitioned between dichloromethane and a saturated solution of sodium bicarbonate (30 mL each). The organic extract was dried over anhydrous sodium sufate, filtered, and concentrated to give 2a as a light brown oil. This amine was used without further purification.
