Reaction Steps

According to Scheme 14 Step 1: A solution of 3-chloro-N-methoxy-1-(4-methoxybenzyl)-N-methyl-1H-pyrazole-4-carboxamide (0.97 mmol, 300 mg) and pyrrolidine (14.5 mmol, 1.03 g) in NMP (10 mL) was stirred at 220° C. for 40 minutes under microwave heating. AcOEt was then added and the organic phase was washed with water. The organic layer was dried over MgSO4, was filtered and was concentrated. The crude compound was purified by flash chromatography with silica gel using cyclohexane/AcOEt (100:0 to 50:50) to yield N-methoxy-1-(4-methoxybenzyl)-N-methyl-3-(pyrrolidin-1-yl)-1H-pyrazole-4-carboxamide (0.87 mmol, 300 mg, 90%) as an oil.
