Versuchsvorschrift

To a suspension of 243 mg of K2CO3 in 15 ml of DMF 450 mg of 5-isopropyl-N-[6-(4-hydroxy-2-butynyloxy)-5-(p-tolyl)-2-(4-pyridyl)-4-pyrimidinyl]-2-pyridine sulfonamide (Example 11) was added. After stirring for 0.5 h at 90° C., 192 mg of 4,6-dimethoxy-2-methylsulfonylpyrimidine was added and stirring was continued for 16 h at 90° C. Eventually, the solvent was evaporated and the remaining residue was partitioned between 50 ml of 10% aqueous acetic acid and 50 ml of DCM. The organic layer was separated and the aqueous layer was extracted two more times with 50 ml of DCM. The combined organic layers were washed with water and brine, dried over MgSO4 and evaporated. The crude product was purified by column chromatography on silica gel eluting with DCM:methanol 20:1 to give 88 mg of 5-isopropyl-N-[6-(4-(4,6-dimethoxy-2-pyrimidinyloxy)-2-butynyloxy)-5-(p-tolyl)-2-(4-pyridyl)-4-pyrimidinyl]-2-pyridine sulfonamide as a beige foam. LC-MS: tR=5.54 min, [M+1]+=668.38, [M−1]+=666.39.
