Procedure
The title product of example 22 (1.09 g, 2.7 mmol) was slurried in ethanol (10 mL) and a solution of 1.4 g NaOH in water (14 mL) was added. The mixture was refluxed 3 hours; then the ethanol was removed with a stream of nitrogen. The aqueous residue was extracted with methylene chloride. The organic phase was washed with brine, dried over calcium sulfate, and concentrated to leave 0.39 g (48%) of the title product. A sample was recrystallized from acetonitrile for analysis: mp 194°-195° C. Analysis calculated for C16H20N4S·CH3CN·0.5 H2O; C, 62.96; H, 6.67; N, 19.32. Found: C, 62.86; H, 6.71; N, 19.69.
