Reaction Conditions

Temperature42 °C

Reaction Steps

At 22° C., 22.4 g (0.746 mol) of paraformaldehyde were added with stirring, over a period of 2 min to a mixture of 100 g (0.746 mol) of methyl N-amino-N-2-hydroxyethylcarbamate in 1500 ml of methylene chloride. After addition of 8.5 g (0.045 mol) of p-toluenesulfonic acid, the mixture was stirred at 42° C. for 21 h, until the precipitate had dissolved, and was then cooled to 20° C., and magnesium sulfate was added. The mixture was filtered and the filtrate was concentrated under reduced pressure. This gave 111.8 g of the title compound as a colorless resin with a GC purity of 85%, corresponding to a yield of 85.8% of theory.
