実験手順

To a solution of 0.52 g of 4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxylic acid, product of example 21, in DMF (10 ml) were added at RT 0.23 g of 1,1,3,3-tetramethylguanidine followed by 0,245 g of acetic acid 1-chloroethyl ester (preparation described by M. Ertan et al., Arzneim. Forsch. 1992, Vol. 42, 70). The reaction mixture was then heated at 60° C. for 20 h, cooled to RT and partitioned between ice water and EtOAc. The organic layer was washed with water, dried over Na2SO4 and the organic layer was removed in vacuo. The residue was purified on a silica gel chromatography column (eluted with tert-butyl methyl ether). Combinations of the purified fractions and evacuation in vacuo afforded 4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxylic acid 1-acetoxy-ethyl ester as a white solid. ISN mass spectrum, m/e 608 (M−1 calculated for C28H27N5O9S: 608).
