1228779-96-1, A mixture of dichloromethane (12.0 L), 2-((lH-pyrrolo[2,3-b]pyridin-5-yl)oxy)-4-(4- ((4′-chloro-5,5-dimethyl-3,4,5,6-tetrahydro[l,r-biphenyl]-2-yl)methyl) piperazin-l- yl)benzoicacid hydrochloride (600.0 g), triethylamine (299.79 g), 4- dimethylaminopyridine (180.97 g), 3-nitro-4-(((tetrahydro-2H-pyran-4- yl)methyl)amino)benzenesulfonamide (342.56 g) and N-(3-Dimethylaminopropyl)-N’- ethylcarbodiimide hydrochloride (283.97 g) was stirred at 25 to 30 degree Celsius for 8h. The reaction mixture was treated with N,N-dimethylethylenediamine (217.63 g) at 20 to 30 degree Celsius and stirred for 4h. The organic layer was washed with water (6.0 L) and concentrated under vacuum. The residue was dissolved in dichlo methane- methanol mixture (1:5) (7.2 L) and treated with acetic acid-methanol mixture (415.11 g acetic acid and 600 mL methanol) and stirred at 20 to 30 degree Celsius. The resulting slurry was cooled to 0 to 5 degree Celsius, filtered and washed with methanol (600 mL). The solid was dissolved in (9:1) mixture of dicloromethane-methanol (4.8 L) at 35 to 45 degree Celsius, diluted with methanol (1680 mL) and stirred for 8h at 20 to 30 degree Celsius. The resulting slurry was cooled to 0 to 5 degree Celsius, filtered, washed with methanol (600 mL) and the solid was dried under vacuum at 60 to 65 degree Celsius for 18 h to provide 4-(4-{ [2-(4-chlorophenyl)-4,4-dimethylcyclohex-l-en-l-yl]methyl}- piperazin-l-yl)-N-({3-nitro-4[(tetrahydro-2H-pyran-4ylmethyl)amino]- phenyl} sulfonyl)-2-(lH-pyrrolo[2,3-b]pyridin-5-yloxy)benz amide. Yield: 70.0% (600g) HPLC Purity: -99.9% 1H NMR data-(DMSO-d6): d 0.921 (s, 6H), 1.204-1.308, 1.598-1.626 (m, d, J=l l.2Hz, 4H), 1.382 (t, J=6.4Hz, 4H), 1.883 (m, 1H), 1.951 (s, 2H), 2.144 (t, br, 2H), 2.199 ( s, br, 4H), 2.754 (s, 2H), 3.073 (s, br, 4H), 3.237-3.291, 3.829-3.865 (m, dd, J=2.8, 3.2, 11.2, l l.6Hz, 6H), 6.189 (d, J=2.0Hz, 1H), 6.388 (dd, J=2.0, 3.6Hz, 1H), 6.678 (d, J=2.0, 2.4, 9.2, 9.6Hz, 1H), 7.037 (d, J=8.8Hz, 2H) 7.11 (d, J=9.2Hz, 1H), 7.34 (d, J=8.0Hz, 2H), 7.495 (m, 2H), 7.535 ( d, J=2.4Hz, 1H), 7.801 (dd, J=2.0, 2.4, 8.8, 9.2Hz, 1H), 8.038 (d, J=2.0Hz, 1H), 8.558 (d, J=2.4Hz, 1H), 8.598 (t, 1H), 11.366 (s, br, 1H), 11.679 (s, 1H).
As the paragraph descriping shows that 1228779-96-1 is playing an increasingly important role.
