Disclosed are a nitrogenous heterocyclic compound, intermediates, a preparation method, a composition and use thereof. The nitrogenous heterocyclic compound in the present invention is as shown in formula I. The compound has a high inhibitory activity towards ErbB2 tyrosine kinase and a relatively good inhibitory activity towards human breast cancer BT-474 and human gastric cancer cell NCI-N87 which express ErbB2 at a high level, and at the same time has a relatively weak inhibitory activity towards EGFR kinase. Namely, the compound is a highly selective small-molecule inhibitor targeted at ErbB2, and hence it has a high degree of safety, and can effectively enlarge the safety window in the process of taking the drug.

2-Methylamino-2-thiazoline reacted with alkyl acyl halides to produce N-acyl-2-methylamino-2-thiazolines, exo-acylated product regioselectively, which were found to be highly chemoselective acylatingagents for primary amine in the presence of secondary amine and for the less sterically hindered of two different primary amines.
