PROCEDURE
实验过程
Following the procedure for Example 282A Step 1, substituting p-methoxyphenylhydrazine for 2,4-dimethylphenylhydrazine hydrochloride and 4,4-difluoro-3-oxopentanenitrile was substituted for 4,4-Dimethyl-3-oxopentanenitrile. Concentration and purification using silica gel chromatography eluting with EtOAc/hexanes (5-40%) afforded 3-(1,1-difluoroethyl)-1-(4-methoxyphenyl)-1H-pyrazol-5-amine in 11% yield. LC-MS (ESI) m/z 254 (M+H)+.
