Procedure
The title compound was prepared in accordance with the general method of Example 34(B), from N-(4-chlorophenyl)pent-4-ynamide (820 mg, 3.95 mmol) and (BOC)2O (1.03 g, 4.74 mmol). The crude residue was purified over silicagel chromatography (prepacked 25 g silicagel column, DCM 100% as eluent) to afford 1.13 g of tert-butyl 4-chlorophenyl(pent-4-ynoyl)carbamate as a colorless oil (Yield: 94%).
