Reaction Steps

To an ice water cooled solution of 6-methoxy-1-(1-methylethoxy)-2-naphthalenecarboxylic acid (5.0 g, 19 mmol) in 50 mL of THF is added 2 drops of DMF followed by oxalyl chloride (2.8 g, 21 mmol). The solution is stirred a room temperature for 2 hours then poured onto 150 mL of aqueous NH4OH. An additional 700 mL of water is added and the resultant precipitate collected. Recrystallization from ethyl acetate provides 6-methoxy-1-(1-methylethoxy)-2-naphthalenecarboxamide in 74% yield; mp 183°-184° C.
