Reaction Conditions

Reaction Steps

Under argon, a solution of 2-(diphenylphosphino)benzaldehyde (522.7 mg, 1.8 mmol) and 2,2-dimethyl-1,3-propanediamine (93.3 mg, 0.9 mmol) in toluene (15 mL) was stirred at room temperature for 15 h. Then the reaction mixture was heated at 80° C. (oil bath) for 2 h 30 min. Next, the solvent was removed in vacuo, and an orange solid was recovered (476.8 mg, 0.74 mmol, 82%).
