Versuchsvorschrift
To a stirred solution of 60 mg (0.19 mmol) (2-amino-5,6-dihydro-4H-cyclopenta[b]thiophen-3-yl)-(3,4-dichloro-phenyl)-methanone (the preparation of which is described in example 1) in 2 ml acetic acid was added 32 mg (0.25 mmol) of 1-cyclopropyl-butane-1,3-dione and one drop of sulfuric acid. The mixture was then stirred at 100° C. for 10 minutes in a microwave and then concentrated in vacuo. Preparative HPLC (30% CH3CN/H20) afforded 24 mg (31%) cyclopropyl-[(4-(3,4-dichloro-phenyl)-2-methyl-6,7-dihydro-5H-cyclopenta[4,5]thieno [2,3-b]pyridin-3-yl)-methanone as a light brown solid. ES-MS m/e (%): 402 (M+H+, 100).
