Zusammenfassung: | The present invention relates to a method of preparing methylpiperidine amino pyrrolo[2,3-d]pyrimidine represented by formula 8 below. The present invention provides a method of preparing methylpiperidine amino pyrrolo[2,3-d]pyrimidine represented by formula 8 below, wherein the method comprises the following steps: a) reacting a compound represented by formula 1 below with a compound represented by formula 2 and a compound represented by formula 3 in which the nitrogen of pyrrole is protected with Boc to obtain a compound represented by formula 4; b) subjecting the compound represented by formula 4 to a high-pressure hydrogen reaction using a Pd catalyst to obtain a compound represented by formula 5, and coupling the compound represented by formula 5 with a compound represented by formula 6 to obtain a compound represented by formula 7; and c) reacting the compound represented by formula 7 obtained in above step b) with hydrochloric acid to neutralize the de-protected hydrochloride with ammonia water.
본 발명은 하기 화학식 8로 표시되는 메틸피퍼리딘 아미노피롤로[2,3-d] 피리미딘의 제조에 관한 것으로서, a) 하기 화학식 1로 표시되는 화합물을 화학식 2, 피롤의 니트로젠이 Boc으로 보호된 화학식 3으로 표시되는 화합물과 반응을 하여 화학식 4로 표시되는 화합물을 얻는 단계: b) 상기 화학식 4로 표시되는 화합물을 Pd 촉매를 이용한 수소 고압 반응으로 화학식 5로 표시되는 화합물을 얻고, 상기 화학식 5로 표시되는 화합물을 화학식 6으로 표시된 화합물과 커플링하여 화학식 7로 표시되는 화합물을 얻는 단계: 및 c) 상기 단계 b)에서 얻어진 화학식 7로 표시되는 화합물을 염산과 반응하여 탈보호된 염산염을 암모니아수로 중성처리하는 하기 화학식 8로 표시되는 메틸피퍼리딘 아미노피롤로[2,3-d] 피리미딘의 제조방법.을 제공한다.JPEG112021020758010-pat00014.jpg41153JPEG112021020758010-pat00015.jpg42160 |
