Reaction Steps

By the procedure of Example 5, 5.0 g. (0.0208 mole) of 3-phenyl-6-methoxybenzothiophene were treated with 3.60 g. (0.021 mole) of o-methoxybenzoyl chloride and 2.80 g. (0.021 mole) of aluminum chloride in 100 ml. of 1,2-dichloroethane as solvent. The crystalline product, 2-(2-methoxybenzoyl)-3-phenyl-6-methoxybenzothiophene (7.52 g.; 97 percent) was obtained from methanol, m.p. 111°-112° C. The product was sufficiently pure to be employed in the next succeeding step; however, a portion of the product was further purified by recrystallization from methanol with the following analytical result.
