Versuchsvorschrift

tert-butyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(aminomethyl)-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)benzoate (200 mg, 0.667 mmol) was dissolved in DMF (10.00 mL) and THF (10.00 mL), ethane-1,2-diylbis(4-methylbenzenesulfonate) (247 mg, 0.667 mmol) was added, followed by K2CO3 (184 mg, 1.333 mmol) and the mixture was stirred at 100° C. until no starting material was detected by LCMS. An M+1=626.7 was observed by LC-MS. The reaction mixture was redissolved in CH2Cl2 (100 mL), washed by water (2×50 mL) and the organic layer was dried over sodium sulfate. The solvent was removed in vacuo and the resultant residue was purified by silica gel chromatography using a mixture of ethyl acetate/hexanes. A white foam was obtained (130 mg, 65%) LCMS: m/e 426.7 (MH+), 4.393 min (method 8). 1H NMR (400 MHz, CHLOROFORM-d) δ 7.90 (d, J=8.3 Hz, 2H), 7.24-7.11 (m, 2H), 5.30 (d, J=1.8 Hz, 1H), 4.70 (d, J=2.0 Hz, 1H), 4.60 (dd, J=2.3, 1.3 Hz, 1H), 2.56 (d, J=21.1 Hz, 1H), 2.44-2.33 (m, 1H), 2.26-2.05 (m, 3H), 2.04-1.89 (m, 1H), 1.86 (d, J=12.0 Hz, 1H), 1.82-1.58 (m, 18H), 1.56-1.37 (m, 7H), 1.35-1.21 (m, 6H), 1.19-1.06 (m, 6H), 1.03 (s, 3H), 0.99 (s, 3H), 0.93 (m, 6H)
