Reaction Steps
In analogy to example 77, from 4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxylic acid, product of example 21, and cyclohexyl 1-chlorethyl carbonate (synthesis described by A. Riondel et al., Tetrahedron, 1988, Vol. 44, 1619) there was obtained 4-[4-methoxy-5-(2-methoxy-phenoxy)-6-(5-methyl-pyridine-2-sulfonylamino)-pyrimidin-2-yl]-pyridine-2-carboxylic acid 1-cyclohexyloxycarbonyloxy-ethyl ester as a white solid. ISN mass spectrum, m/e 692.1 (M−1 calculated for C33H35N5O10S: 692).
