Procedure

82.1 g (0.5 mol) of 1,1,3,3-tetramethoxypropane and 39.7 g (0.45 mol) of 1,3-dimethylurea were dissolved in 400 ml of methanol, 49.0 g (0.5 mol) of concentrated sulfuric acid was added dropwise thereto at room temperature, and the mixture was allowed to undergo the reaction at 50° C. for 30 minutes. After completion of the reaction, this was cooled to room temperature, and the precipitated crystals were collected by filtration to obtain 59.7 g (yield 69%) of the title compound (purity 99.8%, melting point 203-205° C.).
