Procedure
To a solution of tert-butyl 4-[2,4-dioxo-6-phenyl-1-{[3-(propoxymethyl)-1,2,4-oxadiazol-5-yl]methyl]-1,4-dihydrothieno[3,2-d]pyrimidin-3(2H)-yl}piperidine-1-carboxylate (500 mg, compound B69) in DCM (10 ml) is added trifluoroacetic acid (10 ml). After 1 h at RT all volatile materials are removed in vacuo. The residue is taken up in diethyl ether, the resulting precipitate is filtered off, washed with diethyl ether and dried in vacuo to afford the title compound as a solid.
