Participants

Reaction Steps

To a stirred solution of (2-cyclohexyl-5,5-dimethyl-1,3-dioxan-2-yl)methylamine (2.27 g 0.100 mole) in 40 ml of n-hexane/ethylacetate (5:1) is added dropwise at room temperature 2,6-bis(1-methylethyl)phenylisocyanate (1.94 g 0.105 mole). The reaction mixture is stirred at room temperature for two hours. Precipitated solid is filtered, washed with n-pentane/ether (1:1) and dried, yielding 3.85 g of N-[2,6-bis(1-methylethyl)phenyl]-N'-(2-cyclohexyl-5,5-dimethyl-1,3-dioxan-2-yl)methylurea.
