2-((1H-Pyrrolo[2,3-b]pyridin-5-yl)oxy)-4-(4-((4'-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazin-1-yl)benzoic acid

Синтез

A solution of 2 - ((lH-pyrrolo [2,3-b] pyridine-5-yl) oxy) -4- (4 - ((4'-chloro-5,5-dimethyl- 2-yl) methyl) piperazine-1-yl) benzoate (1.65 g, 2.82 mmol, 1.0 eq)Was added to THF (30 mL) and methanol (10 mL), sodium hydroxide (0.60 g, 15.0 mmol, 5.5 eq) and water (6 mL) were added and reacted at 45 ° C overnight. Point half analysis, the raw material has been completely responsive. After cooling, the mixture was poured into 100 mL of water, adjusted to pH = 2 with 2M hydrochloric acid, and extracted with DCM (30 mL x 3). The organic phase was dried over anhydrous sodium sulfate, spin-dried, and then 5 mL of DCM and 100 mL of PE were stirred for 10 min, Filtered to filter the white solid product 2-((1H-Pyrrolo[2,3-b]pyridin-5-yl)oxy)-4-(4-((4'-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazin-1-yl)benzoic acid, the yield 96.9%.
