Versuchsvorschrift
1-(2-Chloroethyl)pyrrole (2.0 g, 15.43 mmol) was combined with a solution of 33% methylamine in ethanol (7.3 mL of 33% w/v, 77.15 mmol). The mixture was heated at 90° C. for 16 h before it was concentrated under reduced pressure to provide N-methyl-2-pyrrol-1-yl-ethanamine (2.19 g, 88%) which was used directly in next reaction. ESI-MS m/z calc. 124.1, found 125.3 (M+1)+; Retention time: 0.22 minutes (3 min run). 1H NMR (400 MHz, CDCl3) δ 6.73-6.68 (m, 2H), 6.22-6.14 (m, 2H), 4.05 (t, J=5.9 Hz, 2H), 2.94 (t, J=5.9 Hz, 2H), 2.45 (s, 3H).
