Procedure
The title compound was prepared in accordance with the general method of Example 34(B), from N-(3-chlorophenyl)pent-4-ynamide (630 mg, 3.03 mmol) and (BOC)2O (795 mg, 3.64 mmol). The crude residue was purified over silicagel chromatography (prepacked 25 g silicagel column 100% DCM as eluent) to afford 824 mg of tert-butyl 3-chlorophenyl(pent-4-ynoyl)carbamate as a colorless oil (Yield: 88%).
