실험 절차

Sodium hydride (1.2 g of 60% in mineral oil) is added to a stirred suspension of 1-cyano-2-benzenesulfonyl-1,2-dihydro-5-methoxyisoquinoline (10 g) in xylene (100 ml). The reaction mixture is refluxed under nitrogen for 3 hrs, cooled to RT, stirred for an additional hour, and filtered. The filtered solid is washed with xylenes. The filtrate is evaporated in vacuo. The filtered solid is stirred with methylene chloride and aqueous 5% sodium hydroxide solution. The methylene chloride phase is combined with the residue from the evaporated filtrate and the combined extracts are washed with 5% sodium hydroxide solution, H2O and dried over sodium sulfate. The dried extract is filtered and the filtrate evaporated in vacuo, affording a moist solid which is triturated in hexanes. The triturated solid is filtered, washed with hexanes, and dried, affording a fluffy orange solid, M.P. 166°-175° C. The crude product is dissolved in ethyl acetate, treated with charcoal, filtered and recrystallized from ethyl acetate, affording the desired cyanoisoquinoline as a crystalline solid, M.P. 180°-182° C.
