| titleOfInvention | Method for synthesizing psoralen derivatives |
| abstract | [Problem] To provide a production method capable of obtaining a high-purity psoralen derivative in a good yield and easily industrialized. As shown in FIG. 1, a compound represented by the formula (II) is acetylated with, for example, 2-chloroacetyl chloride, etc., and led to a compound of the formula (III), and represented by the formula (III). The compound is subjected to Fries rearrangement leading to a compound of formula (IV). A process for producing the compound represented by the formula (IV) by cyclization, reduction and aromatization to lead to the compound represented by the formula (I). In the formula, R 1 is H or a linear / branched C 1 - alkyl group of 6; R 2 is H or a linear / branched C 1 - 6 alkyl group or a linear / branched Jo of C 1 - a 6 alkoxy group. [Selection] Figure 1 |
