Reaction Steps
To a solution of 5-((3R,4R)-3-aminotetrahydro-2H-pyran-4-ylamino)-3-(p-tolylamino)pyrazine-2-carbonitrile in methanol (1 ml) was added K2CO3 (excess) and H2O2 (50%, a few drops). After completion, it was concentrated and purified by preparative HPLC to give 5-((3R,4R)-3-aminotetrahydro-2H-pyran-4-ylamino)-3-(p-tolylamino)pyrazine-2-carboxamide. MS found for C17H22N6O2 as (M+H)+ 343.3, UV: λ=251.2, 302.9.
