Procedure

To a suspension of 9 mg of NaH 55% dispersion in mineral oil in 4 ml of DMF:THF 1:1 was added 50 mg of 4-tert.-butyl-N-[6-(4-hydroxy-2-butynyloxy)-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidin-4-yl]-benzene sulfonamide (Example 14). After the evolution of gas had ceased, 42 mg of 5-bromo-2-chloropyrimidine was added and the mixture was stirred for 1 h at 650C before it was diluted with 50 ml of 10% aqueous citric acid and 50 ml of ethyl acetate. The organic layer was separated, washed with 50 ml of water, dried over MgSO4 and evaporated. The crude product was purified by column chromatography on silica gel eluting with hexane:ethyl acetate 3:2 to give 60 mg of 4-tert.-butyl-N-[6-(4-(5-bromo-2-pyrimidinyloxy)-2-butynyloxy)-5-(2-methoxy-phenoxy)-2-morpholin-4-yl-pyrimidin-4-yl]-benzene sulfonamide as a colourless foam. MS: tR=6.14 min, [M+1]+=739.18, [M−1]+=741.32.
