Reaction Steps

Potassium hydroxide (0.168 g) was dissolved in 7 mL of methanol and 1 mL of water, and the 2-(3-methyl-4-nitrophenyl)malonic acid diethyl ester (0.250 g) obtained in Example 1-3a) was dissolved in the solution. The solution was stirred at 100° C. for 2 hours and concentrated. The residue was acidified with 2N hydrochloric acid and extracted with ethyl acetate. The extract was washed with saturated brine, dried over sodium sulfate and concentrated to give the title compound (0.143 g) as a yellow solid.
