Participants

Reaction Steps

To an ice-chilled solution of 1-(diphenylmethylene)-2-p-tolylhydrazine (270 mg, 0.94 mmol; Example 36A) and N,N-diisopropyl-N-ethylamine (120 mg, 0.94 mmol; Aldrich) in N,N-dimethylformamide (2.0 mL) was added 2-(4-chlorophenyl)acetyl chloride (178 mg, 0.94 mmol; Alfa Aesar). After 10 minutes the ice bath was removed and the reaction mixture was stirred at room temperature overnight (18 hours). The reaction mixture was diluted with water (10 mL) and extracted with dichloromethane (2×20 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated in vacuo to afford the crude product, which was carried on to the next step without further purification: LC/MS m/z 439 (M+H)+.
