Reaction Steps

6-[5-(Tetrahydro-pyran-4-yloxymethyl)-pyridin-3-yl]-3,4-dihydro-2H-[1,8]naphthyridine-1-carboxylic acid tert-butyl ester is synthesized according to the procedure of Suzuki Coupling Method IV, as illustrated above. It is then used to prepare 6-[5-(tetrahydro-pyran-4-yloxymethyl)-pyridin-3-yl]-1,2,3,4-tetrahydro-[1,8]naphthyridine according to the procedure for Step 2 of Example 27 using 20% trifluoroacetic acid in DCM as the reagent.
