Reaction Steps
A mixture of 25.00 g. (0.078 mol) of the product of Procedure 2 and 50 ml. dry pyridine in 50 ml. (0.388 mol) of propionic anhydride was heated at reflux for 3 hr. Upon cooling, a white solid precipitated. CH3CN was added, and the white solid filtered and air-dried to give crystals, mp 278.0°-279.0° (corr.). The material may be recrystallized from DMF-i-PrOH.
