Method for preparing netupitant

The invention discloses a method for preparing netupitant, and belongs to the field of medicine compounds. The method includes the steps: performing condensation on 2-chloro-5-aminopyridine and formicacid; performing reduction, Boc protection and iodination; performing coupling and deprotection and then performing condensation on products and 2-(3, 5-bis-trifluoromethyl-phenyl)-2-methyl propionicacid; performing substitution on products and N-methylpiperazine to obtain the netupitant. The method has the advantages that the steps of processes for preparing the netupitant have fewer side effects, the method is high in yield and less in environmental pollution, after-treatment is simple, and the netupitant which is a product prepared by the aid of the method is high in purity and low in individual impurity content.

Compounds and methods for the prevention and/or treatment of diseases which are pathophysiologically mediated by the neurokinin (NK1) receptor, based on 4-(5-(2-(3,5-bis(trifluoromethyl)phenyl)-N,2-dimethylpropanamido)-4-(o-tolyl)3yridine-2-yl)-1-methyl-1-((phosphonooxy)methyl)piperazin-1-ium and pharmaceutically acceptable salts thereof.

CARBOXYMETHYL PIPERIDINE DERIVATIVE

The present invention provides a new compound which has NK1 receptor antagonist activity, whose CYP3A4 inhibitory activity is reduced compared to aprepitant, and which are useful for the prevention or treatment of cancer-chemotherapy-induced nausea and vomiting. That is, the present invention relates to carboxymethyl piperidine derivatives represented by the following formula (I) or a pharmaceutically acceptable salt thereof. Wherein, ring A is a benzene ring or the like; ring B is a pyridine ring or the like; R1 is C1-6 alkyl or C1-6 alkoxy; R2 and R3 are a hydrogen atom or methyl; and n is an integral number from 0 to 5.

Carboxymethyl piperidine derivative

The present invention provides a novel compound useful in the prevention or treatment of nausea and vomiting associated with the administration of antineoplastics, the compound having an NK1 receptor-antagonizing effect, and an inhibitory effect on CYP3A4 that is attenuated to a greater extent than in aprepitant. Specifically, the present invention relates to a carboxymethyl piperidine derivative represented by formula (I) or a pharmacologically acceptable salt thereof. In the formula, ring A is a benzene ring or the like, ring B is a pyridine ring or the like, R1 is a C1-6 alkyl or C1-6 alkoxy, R2 and R3 are hydrogen atoms or methyl, and n represents an integer of from 0 to 5.
