Participants

Reaction Steps

A mixture of Example 570A (80 mg, 0.2 mmol) and morpholine (35 mg, 0.4 mmol) in 4 mL of toluene was heated under reflux for two hours. After the reaction mixture was cooled to room temperature, it was loaded onto silica gel for purification that yielded 76 mg of the desired product (94%).
