Reaction Steps

6-Methoxy-2-(4-methoxyphenyl)-3-(4-hydroxybenzoyl)benzo[b]thiophene (1.17 g, 3.00 mmol) and 4-hydroxy-1-methylpiperidine (691 mg, 6.00 mmol) were dissolved in 50 mL of anhydrous tetrahydrofuran. This solution was stirred and triphenylphosphine (1.57 g, 6.00 mmol) and diethylazodicarboxylate (DEAD) (6.00 mmol) were added. The resulting solution was allowed to stir at room temperature for 18 hours. The solvent was removed under reduced pressure and the resulting mixture is flash chromatographed (eluent: 7:3 ethyl acetate:methanol) to give 834 mg of the title compound. Yield: 57%. MS(FD) 488(M+). EA calculated for C29H29NO4S: C, 71.43; H, 5.99; N, 2.87. Found: C, 71.14; H, 5.93; N, 2.61.
