Versuchsvorschrift

A mixture of 4-chloro-2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[b]pyridine hydrochloride (0.060 g, 0.20 mmol) and 3-(4-aminophenyl)propanamide (0.066 g, 0.40 mmol) in NMP (3 mL) was microwaved for 3 h at 120° C., then at 140° C. for 2.5 h. After this time, the mixture was purified by silica gel chromatography eluting first with ethyl acetate and hexanes followed by methylene chloride and methanol. The solids were further purified by preparative HPLC to afford the title compound (0.042 g, 54%) as a white solid. MW=391.89. 1H NMR (DMSO-d6, 500 MHz) δ 14.09 (br s, 1H), 9.82 (s, 1H), 7.90-7.89 (m, 1H), 7.71-7.58 (m, 3H), 7.33-7.27 (m, 5H), 6.98 (s, 1H), 6.77 (br s, 1H), 3.18-3.15 (m, 2H), 2.93-2.80 (m, 4H), 2.40-2.34 (m, 2H), 2.27-2.21 (m, 2H); ESI MS m/z 392 [M+H]+.
