The present invention relates to a method for preparing an amide compound, which comprises a step of agitating an alkyne and an N-hydroxy compound in an organic solvent in the presence of a transition metal catalyst to form an amide bond, and a method for preparing a peptide using the same. According to the present invention, the amidation reaction does not depend on polar reactivity, such as the conventional simple nucleophilicity and electrophilicity, but is based on a reaction derived from coordination reactivity between an alkyne and a transition metal, and thus shows excellent chemical selectivity. In addition, the method does not require a consumptive step such as attachment and detachment of a protecting group but includes a simple process during the synthesis of a peptide. Thus, the method is very effective for preparing a polypeptide compound. The method also has 100% of atomic economic efficiency since the starting materials are not lost during the reaction. 본 발명은 전이금속촉매의 존재 하에 알카인 및-하이드록시 화합물을 유기용매 내에서 교반하여 아마이드 결합을 형성시키는 단계를 포함하는 아마이드 화합물의 제조방법 및 이를 이용한 펩타이드 제조방법에 관한 것으로, 본 발명에 의한 아마이드화 반응은 기존의 단순한 친핵성 및 친전자성과 같은 극성 반응성에 의존하지 않고 알카인과 전이금속의 배위결합 반응성에서 도출된 반응을 기반으로 하여 탁월한 화학선택성을 나타낸다. 또한, 펩타이드 합성시 소모적인 보호기 부착 및 탈착 반응 단계를 필요로 하지 않고 반응공정이 간단하여 폴리펩타이드 계열의 화합물을 합성하는데 매우 효과적일 뿐 아니라 반응 도중 출발물질이 소실되지 않기 때문에 100%의 원자경제성을 갖는다.
