実験手順

To a solution of 3-chloro-6,7-dihydro-5H-cyclopentapyridin-7-yl acetate (1.57 g, 7.42 mmole) in MeOH (36 ml) was added aqueous NaOH solution (1M, 8.9 ml, 8.9 mmole) and the mixture was stirred at 22° C. for 1.5 h. The mixture was diluted with water and extracted with dichloromethane, the organic layer was dried and evaporated to give the title compound as a dark red liquid which crystallized on standing. MS (ESI): m/z=170.1 [M+H]+.
