Two compounds have been prepared during the investigation of the reactivity of alpha-halopyruvamides. The reaction products: 3-(4-chlorophenyl)imidazo[1,2-a]pyridine-2-carboxamide (1) and 7-carbamoyl-5-phenyl-2,3-dihydro [1,3] thiazolo [4,3-b] [1,3] thiazol-4-ium chloride (2) were structurally characterized by x-ray crystallography. Compound 1 crystallizes in the ortho rhombic space group Pca2(1) with a = 28.813(2), b = 9.369(1), and c = 9.361(1) Angstrom. The structure contains two crystallographically different molecules. Compound 2 crystallizes in the monoclinic space group P2(1)/c with the following cell parameters: a = 8.5895(8), b = 22.499(2), c = 7.4133(6) Angstrom, and beta = 110.204(1)degrees.
