2-Acetoxyisobutyroyl chloride → 2-[2-[[3-(2,5-Difluorophenyl)-1-benzofuran-5-yl]carbonyl]hydrazino]-1,1-dimethyl-2-oxoethyl acetate

Participants

Reaction Steps

In the same manner as in Reference Example 129 and using 3-(2,5-difluorophenyl)-1-benzofuran-5-carbohydrazide instead of 3-bromo-1-benzofuran-5-carbohydrazide and 2-chloro-1,1-dimethyl-2-oxoethyl acetate instead of (1S)-2-chloro-1-methyl-2-oxoethyl acetate, the title compound (yield 85%) was obtained as colorless crystals.
