Methanol → 5-(13-Cyclohexyl-10-((isopropylsulfonyl)carbamoyl)-3-methoxy-7h-indolo[2,1-a][2]benzazepin-6-yl)-1-ethyl-1h-pyrazole-4-carboxylic acid

Reaction Steps

Ethyl 5-(13-cyclohexyl-10-((isopropylsulfonyl)carbamoyl)-3-methoxy-7H-indolo[2,1-a][2]benzazepin-6-yl)-1-ethyl-1H-pyrazole-4-carboxylate was dissolved in THF (14 mL) and methanol (14 mL) then sodium hydroxide (15 mL, 15.00 mmol) (1.0N aqueous) was added to the reaction. The reaction was placed under a nitrogen atmosphere and stirred at room temperature for 16.5 hrs. The reaction was concentrated in vacuo using a rotary evaporator (bath temp equal to less than 26 C) then partitioned between ethyl acetate and 1.0N aqueous hydrochloric acid. The aqueous layer was extracted with ethyl acetate and the organic extracts combined, washed with brine and dried over magnesium sulfate. The organic solution was filtered and solvents removed in vacuo to give amorphous amber-orange solid (902 mg) after drying at room temperature in vacuo.
