Reaction Steps
To a solution of 4-aminomethyl-4-(2,2,2-trifluoro-acetylamino)-piperidine-1-carboxylic acid tert-butyl ester in MeOH (70 ml) is added a 30% aqueous solution of ammonia (70 ml) and the reaction mixture is stirred at 80° C. overnight. The reaction mixture is concentrated in vacuo to 4-Amino-4-aminomethyl-piperidine-1-carboxylic acid tert-butyl ester as a brown oil that is used crude without further purification; [M+H]+ 230.
