Reaction Steps

To a stirred solution of 1-cyclohexyl-3-(3-oxo-3-(4-(2-oxopyrrolidin-1-yl)piperidin-1-yl)propyl)-2-phenyl-3H-indene-5-carboxylic acid, (46 mg, 0.083 mmol), N,N-dimethylsulfamide (51 mg, 0.42 mmol) and DMAP (51 mg, 0.42 mmol) in dimethylacetamide (1 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (64 mg, 0.33 mmol). The reaction solution was stirred in a sealed tube under nitrogen at 50° C. overnight and purified by reverse phase prep-HPLC to yield 1-cyclohexyl-N-[(dimethylamino)sulfonyl]3-(3-oxo-3-(4-(2-oxopyrrolidin-1-yl)piperidin-1-yl)propyl)-2-phenyl-3H-indene-5-carboxamide as an off-white solid. 1H NMR (500 MHz, CDCl3) δ 8.91 (br s, 1H), 8.09 (s, 1H), 7.92 (d, J=8.5 Hz, 1H), 7.57-7.41 (m, 5H), 6.86 (s, 1H), 5.10 (br s, 1H), 4.41 (br s, 1H), 4.05-3.50 (m, 7H), 3.07 (s, 6H), 2.81 (m, 1H), 2.44 (m, 2H), 2.05-1.38 (m, 16H). LCMS: m/e 658 (M+H)+, ret time 2.43 min, column 3, 2 minute gradient. The next set of experimental procedures constitute a the start of a new section which stand alone:
