Participants

Reaction Steps

To a suspension of the title compound from Step B (60 mg, 0.18 mmol) and thiazolidinedione (21 mg, 0.18 mmol) in dry toluene (2 ml) was added a catalytic amount of piperidinium acetate which was generated by the addition of piperidine (1.5 mg, 0.018 mmol) and acetic acid (1.1 mg, 0.018 mmol). The mixture was heated to reflux under nitrogen for two hours. The solution was cooled, diluted with ethyl acetate (15 ml), washed with 1 N HCl (3×10 ml) and brine (10 ml), dried, filtered, and concentrated. The residue was purified by preparative TLC (5% methanol in dichloromethane) to give the title compound (26.1 mg) as a yellow solid. MS (APCl−) Calc.: 437.0, Found: 436.1 (M−1).
