Reaction Conditions

Reaction Steps

To a solution of N-methyl-2-methylthiophene-3-carboxamide (36.0 g) in THF (500 ml) was added dropwise 2.5M n-BuLi/THF solution (200 ml) at −70° C. The reaction solution was stirred at −70° C. for 2 hr, followed by the addition of anisonitrile (31.0 g) at once. After the dry ice/acetone bath was removed, the reaction mixture was back to room temperature. Three hours later, an aqueous solution of saturated ammonium chloride and ether were added thereto, and then the mixture was further stirred for 1 hr. The resulting white precipitates were collected by filtration, washed with water, ether and n-hexane in this order, and then dried, to give the title compound (17.9 g, yield; 30%).
