Reaction Steps

A solution of 7-tert-butyloxycarbamoyl-1,2-dihydro-2,2-dimethylquinoline (3.4 g, 0.012 mol) in 150 mL of ethyl acetate was hydrogenated under an atmosphere of hydrogen with Pd-C 10% (340 mg) at rt for 7 h. Filtration over celite afforded 3.7 g (100%) of pure 7-tert-butyloxycarbamoyl-1,2,3,4-tetrahydro-2,2-dimethylquinoline. The title compound was prepared by General Method 12 (EXAMPLE 147) from 7-tert-butyloxycarbamoyl-1,2,3,4-tetrahydro-2,2-dimethylquinoline (3.7 g, 0.012 mol) to afford 2.35 g (100%) of 7-amino-1,2,3,4-tetrahydro-2,2-dimethylquinoline as a light reddish oil. Data for 7-amino-1,2,3,4-tetrahydro-2,2-dimethylquinoline: 1H NMR (400 MHz, CDCl3) 6.77 (d, J=7.9, 1H), 6.00 (dd, J=7.9, 2.2, 1H), 5.81 (d, J=2.2, 1H), 3.47 (bs, 1H), 3.40 (bs, 2H), 2.66 (t, J=6.7, 2H), 1.65 (t, J=6.7, 2H), 1.18 (s, 6H).
