75% | With O-(benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium tetrafluoroborate; triethylamine; In (2S)-N-methyl-1-phenylpropan-2-amine hydrate; N,N-dimethyl-formamide; at 20℃; | 3-{1-[6-(3-bromo-7,8-dihydro-5H-1,6-naphthyridin-6-carbonyl)-pyrimidin-4-yl]-piperidin-4-yl}-7-methoxy-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one 90 mg (0.24 mmol) TBTU were added to 80 mg (0.20 mmol) 6-[4-(7-methoxy-2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-pyrimidine-4-carboxylic acid, 70 mg (0.28 mmol) <strong>[1159010-96-4]3-bromo-5,6,7,8-tetrahydro-1,6-naphthyridine-hydrochloride</strong> and 120 muL (0.86 mmol) triethylamine in 0.9 mL DMF and the mixture was stirred overnight at RT. The reaction mixture was combined with 1 mL methanol, 1 mL saturated sodium hydrogen carbonate solution and 8 mL ice water. The precipitate was suction filtered, washed with water and diethyl ether and dried. Yield: 94 mg (75% of th.) ESI-MS: m/z=592/594 (M+H)+ |

74% | With sodium hydrogencarbonate; In tetrahydrofuran; methanol; at 0 - 20℃; | To a suspension of 3-bromo-5,6,7,8-tetrahydro-l,6-naphthyridine hydrochloride (2 g, 8.01 mmol) and NaHC03 (2.02 g, 24.04 mmol) in THF/MeOH (60 mL/60 mL) was added (Boc)20 (1.9 mL, 8.82 mmol) at 0 C. The reaction was stirred at rt overnight, and then concentrated in vacuo. The residue was dissolved in H20 (60 mL), and then extracted with EtOAc (60 mL x 3). The combined organic phases were washed with brine (50 mL), dried over anhydrous a2S04, filtered and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (v/v) = 8/1) to give the title compound as light-yellow sticky liquid (1.87 g, 74%).

A mixture of 4,4,5,5-tetramethyl-2-(2-methylbiphenyl-3-yl)-1,3,2-dioxaborolane (Example 4, Step 1: 20 mg, 0.07 mmol), <strong>[1159010-96-4]3-bromo-5,6,7,8-tetrahydro-1,6-naphthyridine hydrochloride</strong> (AstaTech cat SC2711: 17 mg, 0.068 mmol), [1,1?-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (3 mg, 0.003 mmol) and potassium carbonate (28 mg, 0.20 mmol) in 1,4-dioxane (1 mL) and water (0.5 mL) was degassed and recharged with nitrogen three times. The mixture was then heated and stirred at 110 C. overnight. The crude reaction mixture was purified by prep LCMS (pH 2, acetonitrile/water+TFA) to give the desired product as its TFA salt. LC-MS calculated for C21H21N2(M+H)+: m/z 301.2; found: 301.2. |

400 mg | With sodium carbonate; In tetrahydrofuran; at 25℃; for 5.0h; | To a solution of 3-bromo-5,6,7,8-tetrahydro-1 ,6-naphthyridine hydrochloride (CAS:1159010-96-4, Vendor: PhamaBlock, 300 mg, 1.20 mmol), sodium carbonate (382 mg, 3.61 mmol) in THF (3 mL) and water (3 mL) was added N-[2- (trimethylsilyl)ethoxycarbonyloxyl succinimide (624 mg, 2.40 mmol). After being stirred at 25 C for 5 hrs, the reaction was quenched by addition of saturated NH4C1 (aq. 20 mL), diluted with 50 mL water, extracted with EA (30 mL) three times. The combined organic layer waswashed with water (30 mL) twice and brine (20 mL) once, dried over Na2SO4 and concentrated to give crude product which was purified by flash column (PE/EA = 10/1) to give compound 47a (400 mg) as a white solid.
