PROCESS FOR PREPARATION OF BOCEPREVIR AND INTERMEDIATES THEREOF

THE PRESENT INVENTION RELATES TO AN IMPROVED PROCESS FOR THE PREPARATION OF (1R,5S)-N-[3-AMINO-1-(CYCLOBUTYLMETHYL)-2,3-DIOXOPROPYL]-3-[2(S)-[[[(1,1-DIMETHYLETHYL)AMINO]CARBONYL] AMINO]-3,3-DIMETHYL-1-OXOBUTYL]-6,6-DIMETHYL-3-AZABICYCLO[3.1.0]HEXAN-2(S)-CARBOXAMIDE AND ITS INTERMEDIATES

PROCESS FOR THE SYNTHESIS OF 3-AMINO-3-CYCLOBUTYLMETHYL-2-HYDROXYPROPIONAMIDE OR SALTS THEREOF

A process for preparing 3-amino-3-cyclobutylmethyl-2-hydroxypropionamide of the Formula I: [Chemical formula should be inserted here as it appears in the paper abstract.] or a salt thereof involves providing a compound of the Formula VI described herein in a solution comprising predominately dimethylsulfoxide (DMSO) and converting this compound directly to the compound of the Formula VIII described herein without working up or isolating the intermediate compound of the Formula VII described herein.

Discovery of (1R,5S)-N-[3-amino-1-(cyclobutylmethyl)-2,3-dioxopropyl]-3- [2(S)-[[[(1,1-dimethylethyl)amino]carbonyl]amino]-3,3-dimethyl-1-oxobutyl]-6, 6-dimethyl-3-azabicyclo[3.1.0]hexan-2(S)-carboxamide (SCH 503034), a selective, potent, orally bioavailable hepatitis C virus NS3 protease inhibitor: A potential therapeutic agent for the treatment of hepatitis C infection

Hepatitis C virus (HCV) infection is the major cause of chronic liver disease, leading to cirrhosis and hepatocellular carcinoma, which affects more than 170 million people worldwide. Currently the only therapeutic regimens are subcutaneous interferon-α or polyethylene glycol (PEG)-interferon-α alone or in combination with oral ribavirin. Although combination therapy is reasonably successful with the majority of genotypes, its efficacy against the predominant genotype (genotype 1) is moderate at best, with only about 40% of the patients showing sustained virological response. Herein, the SAR leading to the discovery of 70 (SCH 503034), a novel, potent, selective, orally bioavailable NS3 protease inhibitor that has been advanced to clinical trials in human beings for the treatment of hepatitis C viral infections is described. X-ray structure of inhibitor 70 complexed with the NS3 protease and biological data are also discussed.
