실험 절차

4.19 g of 3-benzyloxycarbonylamino-2,2-dimethylpropionic acid ethyl ester and 50 ml of 33% methylamine (in ethanol) are stirred for 8 days at 60° C. in a bomb tube. The reaction mixture is concentrated by evaporation and the residue is purified by FC (220 g of silica gel, dichloromethane/methanol=95:5). The title compound is obtained: Rf (dichloromethane/methanol=9:1)=0.51.
