Acetamide → 1,3,5-Triazine-2-carbonitrile, 4,6-dimethoxy-

Participants

Reaction Steps

A mixture of 26 g of potassium cyanide and 60 g of oven-dried acetamide was heated to 85°-90° C. To this melt was added 24 g of the product from Example 2 in portions over a period of 15-20 minutes. The resulting brown reaction solution was heated to 90°-100° C. for an additional one hour. When the solution had cooled to room temperature, water was added and the aqueous layer was extracted with ether and methylene chloride. The combined organic extracts were backwashed with several small portions of water, brine, and were then dried over magnesium sulfate and concentrated in vacuo to afford 6.5 g of 2-cyano-4,6-dimethoxy-1,3,5-triazine as a light yellow solid.
