Reaction Steps

This compound is a slightly yellow solid and has been obtained as described in 2b for 1-trityl-4-methoxymethylpyrazole, starting from 1-trityl-4-hydroxymethylpyrazole (1.250 g; 3.67 mmol), sodium hydride (221 mg; 5.51 mmol) and iodoethane (1.5 mL; 18.35 mmol), as described in example 2a for 3,5-dimethyl-4-methoxyethyl-1-tritylpyrazole. Yield: 87% (1.174 g, 3.19 mmol).
