Methanimidic acid, N-cyano-, ethyl ester → N-cyano-N'-[3-[3-(1-piperidinylmethyl)phenoxy]propyl]formamidine hydrochloride

Participants

Reaction Steps

To a solution of 2.48 g of 3-[3-(1-piperidinylmethyl)phenoxy]-1-propanamine (prepared according to British Pat. No. 2,023,123 which is hereby incorporated by reference) in 25 ml of absolute ethanol, are added dropwise 0.98 g of ethyl N-cyano-formimidate in 15 ml of ethanol, under stirring and at room temperature. Stirring is maintained for 30 minutes, and then the ethanol is removed by underpressure distillation. An oil residue is formed, which is then dissolved in 250 ml of ethyl ether, after which 0.95 ml of 10N HCl/ethanol are added, yielding 1.4 g of N-cyano-N'-[3-[3-(1-piperidinylmethyl)phenoxy]propyl]formamidine hydrochloride.
