Procedure

10 g of the 2-methyl-1,1,3-tri(ethoxycarbonylamino)propane obtained in stage 1a) are dissolved in 90 ml of ethanol, 3 g of Raney nickel are added, and hydrogenation is carried out in a stirred autoclave at 165° C. and 50 bar of hydrogen for 10 hours. Conversion is complete, giving 2-methyl-1,3-di(ethoxycarbonylamino)propane with a selectivity of 95%.

Workup

  1. customis carried out in a stirred autoclave at 165° C.
