Compound 22 (0.10 g, 0.18 mmol), Compound 16 (0.055 g, 0.18 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC, 0.052 g, 0.27 mmol)And 4-dimethylaminopyridine (DMAP, 0.044 mg,0.36 mmol) was added to a solution of dichloromethane (20 ml) and stirred at room temperature for 10 h. The reaction was quenched with water (10 mL). Dry over anhydrous sodium sulfate, remove the solvent, The concentrate was subjected to column separation (eluent: ethyl acetate/methanol (v/v) = 30:1), Obtained 50 mg of a yellow solid, The yield was 33%., 1235865-77-6

As the paragraph descriping shows that 1235865-77-6 is playing an increasingly important role.

To a solution of 2-(lH-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4-((2-(4- chlorophenyl)-4,4-dimethylcyclohex- 1 -enyl)methyl)piperazin- 1 -yl)benzoic acid( 16g,28mmol) and 3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)benzenesulfonamide(8.83g, 28mmol) in DCM(300mL) was added EDCI(10.74g, 56mmol) and DMAP(6.85g, 56mmol). The mixture was stirred at r.t. overnight. LC/MS showed the expected product as a single peak. The mixture was diluted with DCM(500ml) and washed with aq. NaHC03, water, brine and dried over Na2S04. The residue after evaporation of solvent was dissolved in DCM and loaded on a column and eluted with 30% ethyl acetate in DCM followed by 1 to 2% MeOH in DCM to give 24.5g pure product(95% purity) which was dissolved in DMSO and MeOH(l :l) and TFA(2eq) and loaded on a 330g C18 column (6g a time)to give 13.5g pure(>99.7% purity) product(55%yield). The API was extracted using dichloromethane and then, the solvent was removed using rotary evaporator. The resulting solid was suspended in acetonitrile at ambient temperatures to reach its solubility. After equilibrating, the solids were isolated at ambient temperature., 1235865-77-6
