While chilling with ice water, hydrogen sulfide gas was introduced into the resultant solution for 5 minutes. After left over for 6 hours at room temperature, water and ethyl acetate were added to the solution to separate liquid layers. An organic layer was washed twice with water and then with saline and then dried over magnesium sulfate. The solvent was distilled out to obtain the intended compound (437 mg). Its physical properties are shown in Table 2 which will be described subsequently.
