Reaction Steps
As in Example 306, a solution of (Z)-5-[2-(2-naphthalenyloxy)ethoxy]-alpha-[(2propenyloxy)imino]-2-thiopheneacetic acid ethyl ester (0.102 g) in methanol (2 mL) and tetrahydrofuran (1 mL) was treated with 4N sodium hydroxide (0.5 mL) and the stirred mixture was heated at 50° C. for 30 minutes. After the normal work up, the product was crystallized from ethyl acetate-hexane to furnish 0.057 g of (Z)-5-[2-(2-naphthalenyloxy)ethoxy]-alpha-[(2-propenyloxy)imino]-2-thiopheneacetic acid, mp 114°-115° C.
