3,5-Dimethylpyrazole → Triethoxy(3-isocyanatopropyl)silane

Participants

Reaction Steps

Into 100 mL of dehydrated ethyl acetate were dissolved 4.81 parts (50.0 parts by mol) of 3,5-dimethylpyrazole and 12.35 parts (50.0 parts by mol) of 3-isocyanatopropyltriethoxysilane, and the solution was stirred at room temperature for 3 days. After the end of the reaction, ethyl acetate was removed to obtain 16.8 parts of a blocked isocyanate compound wherein the isocyanate groups of 3-isocyanatopropyltriethoxysilane were blocked with 3,5-dimethylpyrazole.
