Typical procedure for the formation of imidazolidines: To a solution of substrate monoalkoxycarbonyl diamine (1 mmol) in anhydrous THF (5 mL) was added at room temperature Montmorillonite KSF (400 mg) followed by aqueous 37% formaldehyde (3 mmol). The reaction mixture was stirred at room temperature for 1 h or until the starting material disappeared as monitored by TLC. After filtration, the solvent was removed in vacuo and residue was subjected to flash column chromatography to afford the desired imidazolidine
