Reaction Steps

To a solution of 1,2-bis(4-methoxyphenylmethyl)-4-nitropyrazolidine (0.88 g) in diethylether anhydride (20 ml) was gradually added lithium aluminum hydride (0.38 g) while being cooled with ice. After being refluxed with heating for two hours, the reaction liquid, with an aqueous sodium potassium tartrate solution added thereto, was extracted with ether. The extract was concentrated under a vacuum, thereby yielding 0.80 g of a raw product of the aimed compound.
