Procedure
The above aldehyde (1 equiv) is mixed with NaCN (1.1 equiv), NH4Cl (1.1 equiv) are mixed together in 2 Molar NH3/MeOH (4 equiv NH3). The flask is fitted with a reflux condenser and the mixture is refluxed. At the end of each of the first 3 h an additional equivalent of NH3 in MeOH is added. The reaction mixture is cooled and the excess solids are filtered away on a frit. The filtrate is concentrated by rotary evaporation and the residue is triturated with diethyl ether and the mixture is filtered again. The filtrate is concentrated on a rotovap. The product is purified, if necessary, by flash chromatography on silica with EtOAc/hexanes as an eluent to yield 1-amino-1-cyano-3-(piperid-1-yl)-propane.
