実験手順

To a solution of 12.7 g (0.1 M) 2-(2-thienyl)ethylamine in 20 ml dimethylformamide heated at 55° C. are added, over 10 minutes, 8.05 g (0.1 M) chloromethylmethylether diluted in 10 ml dimethylformamide. After addition of the chloromethylmethylether, the medium is maintained at 70° C. for 2 hours, and is then cooled to room temperature. The desired product precipitates out and is rinsed with acetone, to give 5.5 g 4,5,6,7-tetrahydro-thieno[3,2-c]-pyridine hydrochloride (M.p=225° C.; Yield: 31%).
