Reaction Steps

37% Aqueous formamide solution (6 ml) and sodium cyanoborohydride (1.39 g) were added successively to a solution of 5-[4-(benzyloxy)phenyl]-1-(4-methoxyphenyl)-1H-pyrazol-3-amine obtained by Example 14-2 (2.75 g) in methanol 30 ml. The reaction mixture was stirred at room temperature for 3 days, occasionally adding 37% aqueous formamide solution and sodium cyanoborohydride appropriate amount to consume all starting material.
