Synthetic example 1
[0127] The mercapto compound S1 was synthesized according to Example 4 described in Japanese Patent Application Laid-Open No. 2005-213679. Specifically, 200 g of a solution of 29.6 g (0.1 mol) of pentaerythritol tetraallyl ether in methanol and 2.4 mg (0.02 mmol) of 9-BNN were put into an autoclave with a volume of 300 mL, and the air in the system was purged with nitrogen replacement.
[0128] Then, 23.9 g (0.7 mol) of hydrogen sulfide was introduced into the system, and the resulting mixture was subjected to a reaction for 5 hours while maintaining the temperature in the system at 20°C. After the reaction, the resultant was concentrated under reduced pressure. As a result, the following tetrafunctional mercapto compound S1 was obtained.

Synthetic example 2
[0131] The mercapto compound S2 was synthesized according to Example 1 described in Japanese Patent Application Laid-Open S63-162640. Specifically, 18.0 g (0.1 mol) of inositol, 7.7 g of tetramethylammonium bromide and 25.0 g (0.3 mol) of 48% aqueous sodium hydroxide solution were put into an autoclave having a volume of 300 mL, and the mixture was heated at 90° C. Stir for 1 hour. Then, 23.0 g (0.3 mol) of allyl chloride was introduced into the system, and the resulting mixture was subjected to a reaction for 4 hours while maintaining the temperature in the system at 90°C. Thereafter, 25.0 g of a 48% aqueous sodium hydroxide solution was further added to the resultant, and the mixture was stirred for 1 hour. Then, 23.0 g of allyl chloride was introduced into the system, and the resulting mixture was subjected to reaction for 4 hours. After the reaction, the organic component was extracted using hexane, and then dried under reduced pressure. As a result, inositol hexaallyl ...
