実験手順: To a 50 ml round bottom flask was added 1.17 g (0.005 mol) 2-(1-((6-chloropyridin-3-yl)methyl)imidazolidin-2-ylidene)acetonitrile, 30 ml dry acetonitrile and 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 66% yield. After completion, the mixture was evaporated to remove solvent purified by column chromatography

実験手順: To a 50 ml round bottom flask was added 1.34 g (0.005 mol) (E)-1-((6-chloropyridin-3-yl)methyl)-2-(nitromethylene)-hexahydropyrimidine, 30 ml dry acetonitrile and 0.860 g (0.01 mol) succinaldehyde and catalytic concentrated Hl. 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 38% yield. After completion, the mixture was evaporated to remove solvent purified by column chromatography

実験手順: To a 50 ml round bottom flask was added 1.27 g (0.005 mol) 2-chloro-5-((2-(nitromethylene)imidazolidin-1-yl)methyl)pyridine, 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 71% yield. After completion, the mixture was evaporated to remove solvent purified by column chromatography
