Reaction Steps

To 0.180 g pyrazole in 5 mL DMF is added 0.105 g NaH. After stirring 50 minutes at room temperature, 0.200 g of the material from Step A, above, is added all at once with 5 mL DMF. After 2 hours at room temperature, the reaction is quenched with water and Concentrated in vacuo. The residue is redissolved in ethyl acetate and washed with water, brine, dried over sodium sulfate, filtered and concentrated in vacuo. Flash chromatography eluting with toluene provides 0.181 g (74.8%) of the title compound.
