Procedure

To a suspension of 1-[(2-ethyl-2H-1,2,3-triazol-4-yl)methyl]-6-phenyl-3-(piperidin-4-yl)thieno[3,2-d]pyrimidine-2,4(1H,3H)-dione trifluoroacetate (300 mg; compound B45), 4-[(4aR,10bR)-9-ethoxy-8-methoxy-3,4,4a,10b-tetrahydro-1H-thiopyrano[4,3-c]isoquinolin-6-yl]benzoic acid (217 mg; compound C10), EDCI (104 mg) and HOBT hydrate (74 mg) in DCM (10 ml) DIPEA (0.24 ml) is added. After 14 h at RT water and aqueous potassium hydrogen sulfate solution (10% w/w) are added and the mixture is extracted with DCM. The combined organic layers are dried (sodium sulfate) and concentrated under reduced pressure. The residue is purified by twofold flash column chromatography [silica gel, eluation gradient: DCM/MeOH, 1/0 to 1/1 (v/v)] and preparative HPLC to afford the title compound as a solid.
