YieldReaction ConditionsOperation in experiment
0.5 g With sodium azide; In N,N-dimethyl-formamide; at 60℃; for 5h; To a solution of 0.5 g (3.04 mmol) of <strong>[35170-94-6]4-chloro-[1,8]naphthyridine</strong> in 10 mL of DMF was added 0.39 g (6.08 mmol) of NaN3. The mixture was stirred for 5 h at 60C. The reaction was allowed to cool to roomtemperature and diluted with 300 ml. of EtOAc, washed with water, brine and dried over Na2SO4. The desiccant was filtered off and the solvents were evaporated under vacuum to give 0.5 g of 4-azido-1,8- naphthyridine as a light brown solid.To a solution of 0.5 g (2.92 mmol) of 4-azido-1,8-naphthyridine in 30 mL of THF was added 100mg of 10% Pd/C. The mixture was hydrogenated at 30C under atmospheric pressure for 5 h. The catalyst wasremoved by filtration. The solvent was evaporated to give 420 mg of 1 ,8-naphthyridin-4-amine a crude product as a light brown solid.To a solution of 0.42 g (2.89 mmol) of 1,8-naphthyridin-4-amine in 50 mL of DCM were added 0.64 g (2.89 mmol) of Boc2O, 0.11 g (0.87 mmol) of DMAP and 1.43 mL (8.68 mmol) of DIPEA and then the mixture was stirred at 30C for 16 h. The solvent was removed under vacuum and the residue waspurified by column chromatography eluting with DCM/MeOH (20/1, R1= 0.4) to give 350mg of tertbutyl N-(1 ,8-naphthyridin-4-yl)carbamate as a brown solid.A suspension of 280mg (1.14 mmol) of tert-butylN-(1,8-naphthyridin-4-yl)carbamate and 164 mg (0.12 mmol) of NaH in 2 ml. of THF was stirred at 40C for 16 h. A solution of 0.04 g (0.13 mmol) of 4- bromo-6-(bromomethyl)isoquinoline in 2 mL of THF was added thereto at 3 5C. The mixture was stirredat 35C for additional 0.5 h. The reaction was quenched with saturated aqueous NH4C1 solution. The mixture was diluted with EtOAc and washed with brine. The organic layer was dried over Na2SO4, filtered and concentrated to give the product as a light brown semisolid which was purified by preparative HPLC to give 140 mg of tert-butyl N-[l- [(4-bromo-6-isoquinolyl)methyl] -1, 8-naphthyridin- 1 -ium-4- yl]carbamate as a light brown solid.MS (+ESI): 465.0, 467.0 [M+H].?H NMR (400 MHz, DMSO-d6+ D20) ppm: 9.23 (s, 1H), 9.04 (m, 2H), 8.68 (s, 1H), 8.25 (d, J 8.0 Hz, 1H), 8.13 (d, J= 8.8 Hz, 1H), 7.94 (s, 1H), 7.66 (m, 2H), 7.55 (d, J= 4.8 Hz, 1H), 5.25 (br s, 2H), 1.27 (s, 9H).
