The synthetic route is as follows.<\/p>\n<p>A solution of 3-amino-4-carbethoxy pyrazole (1, 4 g, 1 mmol, 1 equiv) in acetonitrile (60 mL) and sodium hyride (1.5 g, 2 equiv) was stirred in a 250 mL round bottom flask for 1 h under ice cold conditions. Benzylchloride (6 mmol, 1.5 equiv) was added to the reaction mixture and further stirred at room temperature for 12 h. The mixture was extracted with ethyl acetate (3 * 10 mL). The organics were washed, dried on anhydrous Na2SO4, evaporated on a rotary evaporator to afford the crude product. The crude product was recrystallized (MeOH) to get pure compound 6a.
