2-amino-1-[3-(3,4-difluoroanilino)-2-(4-fluorophenyl)-6,8-dihydro-5H-imidazo[1,2-a]pyrazin-7-yl]-2-methyl-propan-1-one → HCID 58178898, compound

Reaction Steps

Example 646 was prepared from Example 29 by the following method: to a stirred solution of Example 29 (12 mg, 0.03 mmol) was added MnO2 (52 mg, 0.60 mmol). The reaction mixture was stirred at room temperature for 2 hours. LC/MS test showed that Example 29 was almost gone and the desired product ([M+1]=528) was detected as one of the major peaks. Solid was filtered off and solvent was removed. The residue was subjected to a mass-triggered HPLC purification to give Example 646.
