실험 절차

The product of Example 240a (1.50 g, 5.63 mmol) was dissolved in DMF to which K2CO3 (1.55 g, 11.27 mmol), and 4-mercapto-phenol (711 mg, 5.634 mmol) were added. The reaction mixture was then heated to 80° C. for 2 hrs. At this point the reaction mixture was cooled to room temperature and diluted with water which was then extracted with ethyl acetate to isolate the desired compound (1.66 g, 79%).
