Reaction Steps
To a solution of Example 89H (0.18 g, 0.42 mmol) in acetonitrile (10 mL) were added mercuric acetate (0.18 g, 0.55 mmol, Aldrich), triethylamine (0.18 mL, 1.27 mmol) and cyanamide (0.04 g, 0.85 mmol, Aldrich). After stirring at 80° C. for 16 hr, the reaction mixture was cooled and quenched with saturated NaHCO3 (20 mL). The aqueous layer was extracted with ethyl acetate (3×20 mL). The combined the organic extracts were washed with water (1×25 mL), dried (Na2SO4), filtered and concentrated. The residue was purified by column chromatography using an Analogix® Intelliflash280 ™ (SiO2, 0-50% ethyl acetate in hexanes) and followed by crystallization from ethyl acetate/hexanes to afford 0.04 g (21%) of the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.86 (d, J=6.8 Hz, 6H), 1.51 (s, 6H), 2.06-2.35 (m, 1H), 2.66-2.87 (m, 2H), 3.81 (s, 3H), 3.94-4.14 (m, 4H), 7.21 (d, J=9.2 Hz, 1H), 7.33 (d, J=2.4 Hz, 1H), 7.52 (dd, J=9.2, 2.7 Hz, 1H); MS (ESI+) m/z 433 (M+H)+; Anal. Calculated C21H25ClN4O2S: C, 58.25; H, 5.82; N, 12.94. Found: C, 58.30; H, 5.79; N, 12.64.
