YieldReaction ConditionsOperation in experiment
With palladium diacetate; In water; at 200.0℃; for 0.08333330000000001h;Microwave irradiation; General procedure: Palladium acetate (56 mg, 0.25 mmol) was added to a mixture of 5-fluoro-2-methoxyphenylboronic acid (850 mg, 5.0 mmol) and (R)-1-(4-bromophenyl)ethylamine (500 mg, 2.5 mmol) in water (20 ml). This mixture was heated for 5 min at 200 C in a Smithcreator microwave oven and then diluted with methanol (200 ml). The mixture was purified on a SCX column (20 g)using 2 M ammonia in methanol to elute the intermediate amine. Evaporation of solvents under reduced pressure gave (R)-1-(50-fluoro-2'-methoxybiphenyl-4-yl)-ethylamine as a gum (580 mg, 2.37 mmol, 96.6%).Triethylamine (41.1 ll, 0.295 mmol) and 1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-sulfonyl chloride (24.5 mg, 0.0984 mmol) were added to a solution of (R)-1-(5'-fluoro-2'-methoxy-biphenyl-4-yl)-ethylamine (20 mg,0.082 mmol) in dichloromethane (1 ml) and the resulting solution shaken at room temperature overnight. Purification by preparative LCMS and removal of solvent under reduced pressure gave 19 (8.5 mg, 40%):

With (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; caesium carbonate; In 1,4-dioxane; water; at 100.0℃; for 0.5h;Microwave irradiation; To a solution of 5-chloro-1-isopropyl-3-methyl-N-((5-methyl-1,3,4-oxadiazol-2-yl)methyl)-1H-pyrazolo[4,3-b]pyridin-7-amine (50 mg, 70 muetaiotaomicronIota) and (2-ethoxypyridin-3-yl)boronic acid (21 mg, 0.13 mmol) in dioxane (2 ml_) and H20 (0.7 ml_) was added Cs2C03(57 mg, 175 muetaiotaomicronIota) and Pd(1 ,1 '-bis(diphenylphosphino)ferrocene)Cl2(10 mg, 14 muetaiotaomicronIota). The mixture was purged with nitrogen for 3 minutes then stirred at 100C for 30 minutes under microwave irradiation. Water (30 ml_) was added and the mixture was extracted with ethyl acetate (30 ml_chi3). The combined organic layers were washed with brine (20 ml_), dried over Na2S04and concentrated. The crude mixture was purified by preparative TLC with dichloromethane: methanol = 20:1 twice, and then the crude product was further purified by preparative HPLC to 5-(2-ethoxy-3-pyridyl)-1-isopropyl-3-methyl-N-[(5-methyl-1,3,4-oxadiazol-2-yl)methyl]pyrazolo[4,3-b]pyridin-7-amine (6.1 mg). 1H NMR (chloroform-d, 400 MHz) delta 8.28-8.26 (m, 1 H), 8.19-8.18 (m, 1 H), 7.23 (s, 1 H), 7.05- 7.02 (m, 1 H), 5.27 (brs, 1 H), 4.96-4.90 (m, 1 H), 4.71 (d, J = 1 .2 Hz, 2H), 4.53-4.48 (m, 2H), 2.65 (s, 3H), 2.57 (s, 3H), 1.66 (d, J = 6.4 Hz, 6H), 1 .43 (t, J = 6.8 Hz, 3H).

The mixture was purged with nitrogen for 3 minutes then stirred at 100C for 30 minutes under microwave irradiation. Water (30 mL) was added and the mixture was extracted with ethyl acetate (30 mL c 3). The combined organic layers were washed with brine (20 mL), dried over Na2S04 and concentrated.
