Procedure
The title compound was prepared following the method described above for the preparation of 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(2-((2-carboxyethyl)(ethyl)amino)ethylcarbamoyl)-5a,5b,8,8,11a-pentamethyl-1-(prop-1-en-2-yl)-2,3,3a,4,5,5a,5b,6,7,7a,8,11,11a,11b,12,13,13a,13b-octadecahydro-1H-cyclopenta[a]chrysen-9-yl)benzoic acid (example 89) using 2-iodopropane as alkylating reagent. The product was isolated as a white solid (12 mg, 66%). LCMS: m/e 715.62 (M+H)+, 2.08 min (method 1). 1H NMR (500 MHz, Acetic Acid-d4) δ ppm 8.03 (d, J=7.93 Hz, 2H), 7.30 (d, J=8.24 Hz, 2H), 5.37 (d, J=4.88 Hz, 1H), 4.78 (s, 1H), 4.65 (s, 1H), 4.00-3.85 (m, 1H), 3.85-3.65 (m, 2H), 3.55-3.32 (m, 4H), 3.23-3.08 (m, 1H), 3.01-2.87 (m, 2H), 2.64-2.47 (m, 1H), 2.27-2.14 (m, 2H), 1.75 (s, 3H), 1.41 (d, J=4.88 Hz, 6H), 2.04-1.10 (m, 19H), 1.08 (s, 3H), 1.06 (s, 3H), 1.06 (s, 3H), 1.01 (s, 3H), 0.99 (s, 3H).
