Reaction Steps

To a stirred solution of 50 mg (0.15 mmol) (2-amino-5,6-dihydro-4H-cyclopenta[b]thiophen-3-yl)-(4-methanesulfonyl-phenyl)-methanone (described above) in 2 ml acetic acid was added 0.011 ml (0.15 mmol) of pentane-2,4-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 18 mg (30%) 1-[4-(4-methanesulfonylphenyl)-2-methyl-6,7-dihydro-5H-cyclopenta[4,5]thieno[2,3-b]pyridin-3-yl)-ethanone as a light brown solid. ES-MS m/e (%): 386 (M+H+, 100).
