実験手順

To a mixture of trans-4-aminocyclohexanol (5.00 g, 43.4 mmol), N,N-dimethylurea (3.82 g, 43.4 mmol), 37% formalin (50 ml), N-methylmorpholine (9.54 ml, 86.8 mmol) and dioxane (10 ml) was added toluene (200 ml), and the mixture was heated for about 5 hours while removing water for azeotropic distillation. Low boiling matters were distilled away from the reaction mixture under reduced pressure, and the residue was purified by silica gel column chromatography (methylene chloride/methanol=50/1-10/1) to give 7.40 g of trans-5-(4-hydroxycyclohexyl)-1,3-dimethylhexahydro-2-oxo-1,3,5-triazine as colorless solid (75%).
