실험 절차
A mixture of 7.2 g (24 mmol) 6,7-dimethyl-4,5-dihydro-thieno[2,3-c]pyridinium iodide and 80 ml of methanol is mixed batchwise 1.87 g (49 mmol) NaBH4 while cooling with an ice bath (vigorous release of gas). The mixture is stirred for another 1.5 h, concentrated, mixed with sat. NaHCO3 solution and extracted 3× with methylene chloride. The organic phases are dried on NaSO4, filtered and concentrated.
