Yield:1193-21-1 100%
Reaction Conditions:
with trichlorophosphate
Steps:
2 Example 2
Example 2 2680 g of phosphorus oxychloride were initially introduced into the reaction vessel and 980 g of 2-methyl-5-ethyl-pyridine were added, while cooling. 460 g of 4,6-dihydroxypyrimidine were then metered in over a period of 1 hour. Further reaction and working up were carried out as described in Example 1. 4,6-Dichloropyrimidine was obtained in a yield of virtually 100% and 88% by weight of the amount of amine employed was recovered.
