Reaktionsschritte
A solution of 130 g of 1,1-dimethylethyl (4piperidinylmethyl)-carbamate in 1300 ml of DMF is treated with 138 ml of triethylamine and 61.8 g of formamidinesulfonic acid and the mixture is stirred at room temperature overnight. The precipitated material is filtered, suspended in 500 ml of ethanol, again filtered off and dried. There are obtained 65.6 g of tert-butyl 1-(aminoimino-methyl)-piperidin-4-ylmethylcarbamate hemisulfite, MS (ISP): 257.4 (M+H)+.
