Versuchsvorschrift
N-methylpyrrolidin-3-amine (0.788 g, 7.87 mmol) was added to 1-fluoro-4-nitrobenzene (1.11 g, 7.87 mmol) slowly (CAUTION: extreme exotherm!!!). The resulting mixture was heated at 110° C. for 10 min. After cooling down to room temperature, another portion of amine (0.156 g) was added to the reaction mixture. The resulting mixture was heated at 110° C. for 1 h. After cooling down to room temperature, the obtained black solid product (Example 43A) was used for next step without further purification. LCMS (ES): m/z 252.3 [M+H]+.
