実験手順

Into the same flask as used in Example 1, triethylamine (5 g), 2-n-pentyl-3-hydroxy-3-methyl-4-cyclopentenone (18.2 g) and toluene (30 g) were charged, and hydrogen sulfide (8 g) was introduced into the mixture at a temperature of 15° to 30° C. Thereafter, the reaction mixture was stirred at a temperature of 50° to 70° C. for 4 hours. After completion of the reaction, the mixture was washed with an acid and water in order. The organic layer was separated and concentrated to obtain 2-n-pentyl-3-methyl-4-mercapto-2-cyclopentenone (18.0 g). Yield, 91%. nD20 1.5212.
