Procedure

To a solution of acetic acid 6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-9-yl ester (53.26 g, 0.259 mol) in methanol (350 mL) was added K2CO3 (72.98 g, mol) and the resultant mixture was stirred at room temperature overnight. The mixture was poured into water (350 mL) and extracted with CHCl3(3×300 mL). The combined organic extracts were dried (Na2SO4), and concentrated to provide 41.70 g of 6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-9-ol.
