Procedure

The title compound was prepared following the method described above for compound (1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-9-(4-(2-carboxyethyl)phenyl)-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]chrysene-3a-carboxylic acid (example 4a) using 3-(2H-tetrazol-5-yl)phenylboronic acid as the reactant boronic acid. The product was isolated as a white solid (4.56 mg, 26%). LCMS: m/e 581.53 (M−H)−, 4.12 min (method 3). 1H NMR (400 MHz, <DMSOmix>) δ ppm 0.95 (d, J=4.10 Hz, 6H), 0.99 (s, 3H), 1.01 (s, 6H), 1.03-1.76 (m, 17H), 1.69 (s, 3H), 1.81-1.93 (m, 2H), 2.07-2.23 (m, 2H), 2.34 (dd, J=13.47, 2.34 Hz, 1H), 2.95-3.06 (m, 1H), 4.58 (s, 1H), 4.72 (s, 1H), 5.32 (d, J=4.39 Hz, 1H), 7.22 (d, J=6.44 Hz, 1H), 7.38-7.51 (m, 1H), 7.81 (s, 1H), 7.92 (d, J=7.32 Hz, 1H).
