Procedure
87.0 g (0.29 mol) of ethyl 2-(4,5,6-trichloronicotinoyl)acetate are heated with 56.2 g of (0.38 mol) of ethyl orthoformate and 65.2 g of acetic anhydride at 150°-160° C. for two hours. All volatile components are removed, initially in vacuo and then under a high vacuum up to 100° C.
Workup
- customAll volatile components are removed, initially in vacuo
- customup to 100° C.
