Source of material

To 2-aminothiazole (0.1 mol) dissolved in the least amount glacial acetic acid bromine (0.11 mol) also dissolved in glacial acetic acid was added dropwise with continuous stirring at room temperature. The mixture was heated at 80°C for 90 min, stirred for 12 h at room temperature and then filtered and washed with water. The precipitate was heated in an ammoniacal alkaline aqueous solution, filtered, washed with water, dried and crystallized from ethanol to give ethyl 2-amino-5-bromothiazole-4-carboxylate, M.P. 115–17°C [1].

Experimental details

Cell refinement and data reduction were carried out by Bruker SAINT and APEX2 [8]. The hydrogen atoms were placed on calculated position (AFIX 23, 93 or 137 option of the SHELX program [9]).

Discussion

2-Aminothiazole derivatives are often used structural motifs in medicinal chemistry due to their broad application in drug synthesis. Several reviews and papers regarding the applications of 2-aminothiazoles in the treatment of a diverse range of different diseases like alzheimer's disease [2], chronic pain [3], cancer [4] and Huntington's disease [5] appeared over the last few years.

The asymmetric unit of the title structure, contains two independent molecules, which show great similarity in bond lengths and angles. The 2-aminothiazole ring and the ethyl carboxylate group are almost planar. All geometric parameters are in excellent agreement with those found for the 4-phenyl analogues [6, 7]. The similarity of these two structures extends to their hydrogen-bonding motifs. The molecules in the title structure are connected via three intermolecular hydrogen bonds, N1A—H1AA⋯N2Ai, N1B—H1BA⋯O1Bii and N1B—H1BA⋯N2Bii. The H⋯A distances are 2.12, 2.57 and 2.16 Å, respectively and the angles are 165, 122 and 163°, respectively. Symmetry codes: (i) −x+1, −y−1, −z+1; (ii) −x+2, −y+1, −z+1.
