Process for producing a sars-cov-2 3cl pro inhibitor
A recently filed patent (Publication Number: US20230295175A1) describes a process for producing a compound of Formula (A). The process involves several steps and conditions, as outlined in the claims.
In the first claim, the process for producing the compound is described. The subsequent claims provide additional details and variations of the process. For example, claim 2 specifies that when R1 is F (fluorine) and R2 is isobutyl, the process is conducted. Claim 3 further specifies that when G1 is methyl, X is Cl- (chloride ion), and PG1 is Cbz (carbobenzyloxy), the process is conducted.
The claims also outline the specific conditions and reagents used in each step of the process. For example, in step (b), the reaction is conducted in the presence of di-tert-butyl dicarbonate (Boc anhydride) as a Boc protection reagent and triethylamine as a base. In step (c), the reaction is conducted in the presence of N-bromosuccinimide (NBS), acetic acid, at a temperature of about -30° C., and the ratio of diastereomer (d-1) to diastereomer (d-2) is from 6:1 to 8:1. Similar details are provided for the other steps of the process.
Claims 5 to 8 and claims 9 to 11 describe alternative processes for producing the compound of Formula (A) with variations in the reagents and conditions used in each step.
Overall, the patent claims describe a detailed process for producing a compound of Formula (A) with specific variations and conditions. The process involves multiple steps and the use of various reagents and catalysts. The claims provide a comprehensive overview of the process and its variations, allowing for potential applications in the field.
