Ethyl 4-(furan-2-yl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate: a triclinic polymorph

The title compound, C12H14N2O4, crystallizes in the triclinic space group P-1. The previously reported polymorph occurs in the monoclinic space group P21/c, and has two independent molecules in the asymmetric unit [Wang (2010). Acta Cryst. E66, o2822]. The dihydropyrimidine ring adopts a screw-boat...
