Versuchsvorschrift

To a solution of 250b (3.0 g, 11.4 mmol) in dichloromethane (30 mL) was added the solution of CH3NH2 (3.0 g, 34.2 mmol, 35% in water). This reaction mixture was stirred at room temperature for 1 h. Then the organic layer was separated, dried over Na2SO4, and filtered. The filtrate was concentrated under reduced pressure to afford 250c (1.9 g, 78%) as yellow solid. MS-ESI: [M+H]+ 215.3
