Reaction Steps

In analogy to the procedure described for the preparation of example 45, 6-(5-bromo-pyridin-3-yl)-1-methyl-3,4-dihydro-1H-quinolin-2-one (prepared from 1-methyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-1H-quinolin-2-one (intermediate A-1) and 3,5-dibromo pyridine also with a procedure as used for the preparation of example 45) has been coupled to 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester to give the title compound as an amorphous colorless solid. MS: 420.5 (M+H+).
