Crystal structure of 2-acetyl-5-(3,4-dimethoxyphenyl)-6-ethoxycarbonyl-3,7-dimethyl-5H-thiazolo[3,2-a]pyrimidin-8-ium chloride

Crystal structure of 2-acetyl-5-(3,4-dimethoxyphenyl)-6-ethoxycarbonyl-3,7-dimethyl-5H-thiazolo[3,2-a]pyrimidin-8-ium chloride

The title molecular salt, C21H25N2O5S+·Cl−, crystallizes with two ion pairs in the asymmetric unit. The cations have similar conformations (r.m.s. overlay fit = 0.40 Å), with one of them showing disorder of the terminal methyl group of the ester in a 0.72 (2):0.28 (2) ratio. In the first cation, the...
