Reaction Steps
To a solution of pyrazole (100 mg, 1.50 mmol) in DMF (10.0 ml) under nitrogen atmosphere was added sodium hydride (60 mg, 1.65 mmol) and the solution stirred for 5 min. After bubbling ceased, the title compound from Step A (204 mg, 1.50 mmol) in 2.5 mL of DMF was added to the solution. The mixture was placed in a microwave reaction vessel and nitrogen was blown into it before closing.
