Procedure

Placed 245.12 mg of the product of Example 49-7 into a 10 mL receiver flask. Added 6 mL of 50/50 ethanol/water. Warmed to in an oil bath on a hot-plate set to 90° C. and added 29.02 mg of potassium hydroxide. Solution clarified. Cooled in 10° C. increments to 55° C. Solid precipitated. Cooled to 40° C. and held for ˜1 hour. Cooled to ambient temperature and stirred overnight. Collected solid via vacuum filtration the next morning and dried the solid at 50° C./vacuum for 3 days.
