Application of 1009102-44-6, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1009102-44-6 as follows.
To a solution of (E)-3-((3aS,5aR,5bR,7aR,9S,11aR,11bR,13aS)-9-hydroxy-1- isopropyl-5a,5b,8,8, 11 a-pentamethyl-2-oxo- 3,3a,4,5,5a,5b,6,7,7a,8,9,10,11,11a, 11b, 12,13, 13a-octadecahydro-2H- cyclopenta[a]chrysen-3a-yl)-2-methylacrylic acid (350 mg, 0.685 mmol), 1-(4- chlorophenyl)cyclopropanamine hydrochloride (154 mg, 0.754 mmol) and HATU (521 mg, 1.371 mmol) in DMF (2 mL) stirred at 0C was added DIPEA (0.479 ml_, 2.74 mmol). The reaction mixture was stirred at 20C for 1h. The reaction mixture was pH adjusted to 3-4 with 2 M HCI and filtered. The solid was washed with water (50 mL), dissolved into DCM, dried over sodium sulfate and evaporated in vacuo to give the crude (E)-N-(1-(4- chlorophenyl)cyclopropyl)-3-((3aS,5aR,5bR,7aR,9S, 11 aR, 11 bR, 13aS)-9-hydroxy-1 – isopropyl-5a,5b,8,8, 11 a-pentamethyl-2-oxo- 3,3a,4,5,5a,5b,6,7,7a,8,9,10,11,11a, 11b, 12,13, 13a-octadecahydro-2H- cyclopenta[a]chrysen-3a-yl)-2-methylacrylamide (650 mg, 0.680 mmol, 99 %) as a yellow solid.
