Trifluoroacetic acid → HCID 178450370, compound

Participants

Reaction Steps

To a solution of 2-(butyloxy)-8-(methyloxy)-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (7.34 g) in methanol (100 ml) was added trifluoroacetic acid (10 ml). The mixture was stirred at ambient temperature over the weekend to give a suspension. The reaction mixture was concentrated to a small volume (thick slurry) before being diluted with ethyl acetate (50 ml). The resultant slurry was filtered and washed with a small volume of ethyl acetate until the filtrate was colourless. The solid remaining was dried by air and then in vacuo to give the title compound as a white solid (6.20 g).
