PROCEDURE

实验过程

On heating in ethanol with the addition of a trace of sulphuric acid, 1,4-dihydro-2,6-dimethyl-3-nitro-4-(trifluoromethylphenyl)-pyridine-5-carboxylic acid (obtained as described in Example 30) was decarboxylated to give 1,4-dihydro-2,6-dimethyl-3-nitro-4-(trifluoromethylphenyl)pyridine in quantitative yield. Melting point 201° C.
