Reaction Steps

A mixture of Example 81C (400 mg, 1 mmol), 2-mercaptoacetamide (183 mg, 2 mmol) and potassium carbonate (277 mg, 2 mmol) in DMA (10 mL) was heated at 50° C. for 14 hours. The mixture was then poured into water and extracted with ethyl acetate. The acetate layer was washed with brine, dried with MgSO4, filtered, and concentrated under reduced pressure. Purification by chromatography (SiO2, EtOAc-MeOH: 9:1) afforded 235 mg of the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.81-1.02 (m, 3H), 1.27-1.44 (m, 11H), 1.56-1.78 (m, 2H), 3.55 (s, 2H), 3.88 (s, 3H), 4.27-4.50 (m, 2H), 6.83 (s, 1H), 7.12 (s, 1H), 7.41-7.73 (m, 3H), 8.32 (d, J=2.0 Hz, 1H). MS (ESI+) m/z 471 (M+H)+. Anal. calculated for C22H29F3N4O2S.0.25H2O: C, 55.62 H, 6.26 N, 11.79. Found: C, 55.46 H, 6.32 N, 11.50.
