A slurry of the product of Example 304A (15 g, 0.061 mol) in ethanol (100 mL), was treated with sodium carbonate (6.41 g, 0.061 mol) and benzyl mercaptan (7.5 mL, 0.058 mol) in water (50 mL). The reaction mixture was refluxed for 5 hours, cooled to 25° C. and poured into of distilled water (800 mL). The resulting slurry was stirred forl hour at 25° C. and filtered. The resulting yellow solid was washed with water and dried in a vacuum oven at 50° C. to give the title compound (20.53 g). 1H NMR (300 MHz, DMSO-d6) δ ppm 4.35 (s, 2 H) 5.27 (s, 2 H) 7.02 (dd, J=9.19, 2.57 Hz, 1 H) 7.16 (d, J=2.57 Hz, 1 H) 7.40 (m, 10 H) 8.24 (d, J=9.19 Hz, 1 H).
