Procedure
To a mixture of 260 mg of 4-tert.-butyl-N-[6-chloro-5-(o-methoxyphenoxy)-2-(2-pyrimidinyl)-4-pyrimidinyl]benzene sulfonamide (Example 5a) and 1.50 g of 4-phenoxy-2-butyn-1-ol (prepared starting from phenyl-propargylether and para-formaldehyde following the procedure given in J. Chem. Soc. Perkin Trans. 1, 1991, 1721-1727) in 15 ml THF was added 184 mg of 55% NaH in mineral oil. The suspension was stirred for 1 h at reflux. The reaction mixture was cooled, diluted with 100 ml 10% aqueous citric acid and extracted 4 times with 50 ml of ethyl acetate. The combined organic phases were washed with water, dried over MgSO4 and evaporated. The crude product was purified by chromatography on prep. tlc-plates with ethyl acetate:methanol:sat. aqueous ammonia 8:2:1 to give 82 mg of 4-tert.-butyl-N-[6-(4-phenoxy-2-butynyloxy)-5-(o-methoxy-phenoxy)-2-(2-pyrimidinyl)-4-pyrimidinyl]benzene sulfonamide as a slightly yellow foam. LC-MS: tR=5.60 min, [M+1]+=652.63, [M−1]−=650.58.
