Methyl 2-[(tert-butoxycarbonyl)amino]-3-(3-methyl-2-sulfanylidene-2,3-dihydro-1H-imidazol-1-yl)propanoate

In the title compound, C(13)H(21)N(3)O(4)S, the mean plane of the -N(H)-C(=O)-O- group of the carbamate unit forms a dihedral angle of 64.7 (2)° with the mean plane of the -C-C(=O)-O- group of the ester unit. In the crystal, mol-ecules are linked by N-H⋯O=C hydrogen bonds, forming chains along the c-axis direction.
