Procedure

To a solution of N-methylbenzenamine (110 mg, 1.02 mmol) in DCM (3 mL) was successively added at R.T. 4-pentynoic acid (100 mg, 1.02 mmol), HOBT (171 mg, 1.12 mmol) and EDCI.HCl (293 mg, 1.53 mmol). The reaction was stirred at R.T. overnight. The reaction was quenched with water. The organic layer was separated and washed with 1M NaHCO3 and water. The solvent was removed under reduced pressure to afford 150 mg N-methyl-N-phenylpent-4-ynamide (Yield: 78%) as an orange oil which can be used without further purification.
