実験手順

To a flask containing (1S,3aS,5aR,5bR,7aS,9S,11aS,11bR,13aR,13bR)-1-isopropyl-9-(4-(methoxycarbonyl)phenyl)-5a,5b,8,8,11a-pentamethylicosahydro-1H-cyclopenta[a]chrysene-3a-carboxylic acid (0.154 g, 0.267 mmol) was added oxalyl chloride (2M in dichloromethane) (5 mL, 10.00 mmol). The solution was stirred at rt for 3 h. The mixture was concentrated under reduced pressure and was dissolved in dichloromethane and concentrated two additional times. The crude product was used in the next step with no additional purification.
