Reaction Steps

A fine-powder crystal of 2-ethyl-3-(2-furyl)acrylic acid anhydride was prepared from 2-ethyl-3-(2-furyl)acrylic acid in the same manner as in Example 1. Then, the fine-powder crystal was dissolved in acetone and the acetone was evaporated by circulating an argon gas in the same manner as in Example 1 to form a single crystal of 2-ethyl-3-(2-furyl)acrylic acid anhydride having a size of 5×2×1.5 mm. The single crystal was fixed on a goniohead and irradiated with Nd:YAG laser light (wavelength; 1064 nm). The output of the second harmonic wave in green was very low.
