Application In Synthesis of tert-Butyl 3-(trifluoromethyl)-4,5-dihydro-1H-pyrazolo[3,4-c]pyridine-6(7H)-carboxylate

Description 21 : 6-methyl-3-(trifluoromethyl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4- c] pyridineUnder an inert atmosphere of argon, LiAIH4 (2.3 M in THF; 7.5ml; 17.3mmol) was added dropwise over 2 minutes to a cool (O0C) stirring solution of 6-tert-butoxycarbonyl-3- (trifluoromethyl)-4,5,6,7-tetrahydro-1 H-pyrazolo[3,4-c]pyridine (2.0Og; 8.45mmol) in anhydrous THF (42ml). The resulting mixture was stirred in an oil bath at 580C for 17 hours, cooled to O0C, and quenched by the careful addition of an aqueous solution of sodium potassium tartrate (1 M; 50ml). After stirring at room temperature for 1 hour, the mixture was diluted with diethyl ether (50ml) and more aqueous sodium potassium tartrate (1 M; 50ml). After stirring at this temperature for a further 1 hour, the mixture was partitioned between water (100ml) and diethyl ether (200ml). The separated aqueous phase was extracted with ethyl acetate (200ml), and the combined organic phase was dried (MgSO4) and concentrated in vacuo. The resulting off-white solid (1.39g) was purified using an SCX column giving the title compound as a yellow solid (1.23g; 6.01 mmol)LC/MS (ES): Found 206 (ES+), retention time 1.81 mins. C8H10F3N3 requires 205.1 H-NMR (400MHz, CDCI3): 2.48 (3H, app s), 2.74 (4H, app s), 3.58 (2H, app s), 5.01(1 H, br s)

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,733757-89-6, its application will become more common.
