PROCEDURE

实验过程

As for Example 6, 99 g. of 3-thiophenecarboxaldehyde is converted to α-(3-thienyl)-4-morpholineacetonitrile (137 g.; m.p. 85°-87° C.). The preceding compound 50.5 g. is reacted with 100 ml. of ethyl acrylate in 500 ml. of tetrahydrofuran in the presence of 50 ml. of 30% potassium hydroxide in ethanol. The solvent is removed from the reaction mixture and the residue is heated with 6 N hydrochloric acid to give 3-(3-thenoyl)propionic acid. As for Example 1, the preceding compound is converted to the product of the Example to give a glass.
