Reaction Steps

(E)-N′-(3,4-Dimethoxybenzylidene)-2-methoxy-N-methyl-2-phenylacetohydrazide (12-70) was synthesized according to the method used for the preparation of Example 6. To a solution of (E)-N′-(3,4-dimethoxybenzylidene)-2-methoxy-2-phenylacetohydrazide (12-21) (0.56 g) in anhydrous DMF in an oven-dried flask under argon was added iodomethane (1 eq) then NaH (60% in oil; 1.1 eq) was added and the mixture stirred for 2 hours. The reaction was quenched with brine and further diluted with water. The aqueous mixture was extracted with EtOAc and the combined organics were washed with water three times, brine once, dried over Na2SO4 and concentrated in vacuo. Purification by chromatography provided the product (12-70) (0.4 g, 70%).
