Product 1

HCID 86679204(R)-2-Methyl-propane-2-sulfinic acid [4-methyl-5-(1-methyl-2-oxo-1,2,3,4-tetrahydro-quinolin-6-yl)-pyridin-3-ylmethyl]-amide

Procedure

In analogy to the procedure described for the preparation of example 45, 1-methyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,4-dihydro-1H-quinolin-2-one (intermediate A-1) has been coupled to (R)-2-methyl-propane-2-sulfinic acid (5-bromo-4-methyl-pyridin-3-ylmethyl)-amide (intermediate A-59) to give the title compound as a colorless amorphous solid. MS: 386.5 (M+H+).
