Reaction Steps

To a 50 ml round bottom flask was added 1.30 g (0.005 mol) 1-((2-chlorothiazol-5-yl)methyl)-2-(nitromethylene)imidazolidine, 30 ml dry acetonitrile, 0.860 g (0.01 mol) succinaldehyde and catalytic concentrated HCl. The reaction was stirred at r.t. and monitored by TLC. After completion, the mixture was evaporated to remove solvent and purified by column chromatography to afford final product as faint yellow powder with 63% yield.
