Reaction Conditions

Reaction Steps

N,N-dimethylformamide dimethyl acetal (5.97 g) and 10 ml of toluene were added to 1.09 g of the 2,5-dimethyl-4-(2-trimethylsilyl-1-ethynyl)aniline (Compound 4-27) produced in Production Example 3, and the mixture was stirred at 110° C. for 9 hours. The reaction solution was concentrated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=5:1), thereby obtaining 0.56 g of N,N-dimethyl-N′-[2,5-dimethyl-4-(2-trimethylsilyl-1-ethynyl)phenyl]formamidine (Compound 59).
