Versuchsvorschrift
5-(2-Fluorophenyl)-1H-pyrrol-3-carboxaldehyde 1d (1.89 g, 10 mmol, prepared by a known method disclosed in “Journal of Medicinal Chemistry”, 2012, 55(9), 4446-4456) was dissolved in 20 mL of methylamine, and the reaction solution was stirred for 1 h. Sodium borohydride (1.14 g, 30 mmol) was added and continuously stirred for 1 h. 10 mL of water were added to the reaction solution, and the reaction solution was concentrated under reduced pressure to obtain the title product 1-(5-(2-fluorophenyl)-1H-pyrrol-3-yl)-N-methylmethanamine 1e (2.0 g, a yellow oil), which was used directly in the next step.
