Reaction Steps
The obtained 6-chloro-3-methyl-1-phenyluracil (4.26 g, 18 mM) was added to 100 ml of 2-propanol. A 40% aqueous solution of methylamine (17 g, 0.22M) was added to the resulting solution and the mixture was heated at 90° C. for 5 hours while stirring. After being left to cool, a precipitated crystal was obtained by filtration and washed successively with ethanol and water to yield 3-methyl-6-methylamino-1-phenyluracil (yield: 3.71 g, or 89% based on 6-chloro-3-methyl-1-phenyluracil).
