Yield:175013-18-0 83%
Reaction Conditions:
with potassium carbonate in N,N-dimethyl-formamide;propan-2-one; for 7 h;Reflux;
Steps:
2.5 Example 2
(5) Dissolving methyl N-methoxy-N- (2-bromomethylphenyl) carbamate with DMF as solvent0.12 mol of 1- (4-chlorophenyl) -pyrazolol, 0.15 mol of K2CO3 and acetone were placed in a reactor. After the temperature was raised to reflux, a solution of 0.1 mol of N-methoxy-N-2-bromomethylphenylcarbamate solution was refluxed for 7 hours. After filtration and drying, the solid material was completely dissolved by stirring with anhydrous methanol, and then cooled and crystallized to obtain a light The yellow solid is the target product pyraclostrobin.
The purity of the product pyraclostrobin prepared by the above method was 89.1% and the yield was 83%
