Procedure

The mixture of (1R,3aS,5aR,5bR,7aR,11aR,11bR,13aR,13bR)-3a-((2-(1,1-dioxidothiomorpholino)ethyl)amino)-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 trifluoromethanesulfonate (50 mg, 0.070 mmol), ethyl 1-((tert-butoxycarbonyl)amino)-2-vinylcyclopropanecarboxylate (17.76 mg, 0.070 mmol) and N-cyclohexyl-N-methylcyclohexanamine (0.018 mL, 0.083 mmol) in dioxane (1 mL) was placed in a sealable pressure tube and N2 was bubbled through the solution for 10 min. Bis(tri-tertbutylphosphine) Palladium(0) (0.355 mg, 0.695 μmol) was added to the reaction mixture and the tube was sealed, and heated to 110° C. for 4 h. After cooling to rt, the crude reaction mixture was diluted with diethyl ether and filtered. The filtrate was concentrated and purified using a flash silica gel column (4 g; eluted with ethyl acetate in hexane from 0 to 45%) to give the title compound as a yellow film (13 mg, 22.7%). MS: m/e 824.55 (M+H)+, 2.625 min (method 4). 1H NMR (400 MHz, CHLOROFORM-d) δ 7.23-5.36 (m, 2H), 5.27-5.12 (m, 1H), 4.72 (br. s., 1H), 4.61 (br. s., 1H), 4.26 (m, 2H), 3.24-2.92 (m, 8H), 2.72-2.45 (m, 5H), 2.32-1.76 (m, 11H), 1.68 (br. s., 3H), 1.53-0.74 (m, 42H).
