    Process for the Preparation of an Amorphous, Peptide-like Diabetes Drug: Approach to a Chromatography-Free Process
    摘要:
    A manufacturing process suitable for large-scale production of the peptide-like amorphous compound N-((R)-1-{(3R)-6-chloro-3-[(dimethylamino)methyl]-3,4-dihydroquinolin-1(2H)-yl}-3-(H-indo1-3-yl)-1-oxopropan-2-yl)-1-[(1-methyl-1H-indol-2-yl)carbon-yl]piperidine-4-carboxamide (1) as a drug for treating diabetes has been developed. The first kilogram quantities of 1 were prepared via a single-chromatography process that employed recyclable cation-exchange resin chromatography for an amorphous intermediate (2R)-2-amino-1-[(3R)-6-chloro-3-[(dimethylamino)methyl]-3,4-dihydroquinolin-1(2H)-yl]-3-(1H-indol-3-y1)-propan-1-one (syn-3a). We have also developed a chromatography-free process that involves a combination purification of extraction of syn-3a with crystallization of syn-3a center dot 0.25H(3)PO(4)center dot 0.5H(2)O. The latter process afforded amorphous compound 1 with >98% purity by HPLC area analysis, the same quality as that provided by the former process.

    This paper reports a room temperature visible‐light‐driven protocol for the intermolecular [2+2] cycloadditions between coumarin‐3‐carboxylates and acrylamides analogs by an energy‐transfer process. Using an iridium complex FIrPic as a photosensitizer and a 3 W blue LED as a light source, an array of cyclobutabenzocypyranones were prepared in moderate to excellent yields.
