Reaction Conditions

Reaction Steps

A solution of 3-(1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrazol-4-yl)benzonitrile (110.0 mg, 0.0003673 mol) was taken up in TFA (3.0 mL, 0.039 mol) and the mixture was heated in microwave at 120° C. for 3 min. The reaction mixture was allowed to cool to rt, and then concentrated to give a crude residue. The product was purified by HPLC on a C-18 column eluting with a water/ACN gradient containing 0.2% TFA to give 3-(1H-pyrazol-4-yl)benzonitrile trifluoroacetate as an amorphous white solid, LC/MS (M+H)+: 170.
