Steps:
2.c Preparation of methyl 3-methoxy-2,4,5-trifluorobenzoate
c) If Example 2b) is repeated, but the abovementioned amount of diphenylmethane is already added during the methylation, 17.4 g (79 mmol) of methyl 3-methoxy-2,4,5-trifluorobenzoate are obtained corresponding to 90.5% yield, based on 4-hydroxy-3,5,6-trifluorophthalic acid employed.
