Reference 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 soution of (E)-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)acrylic acid (500 mg, 1.007 mmol), 1-(4- chlorophenyl)cyclopropanamine hydrochloride (226 mg, 1.107 mmol) and HATU (765 mg, 2.013 mmol) in Nu,Nu-dimethylformamide (DMF) (2 mL) stirred at 0C was added DIPEA (0.703 mL, 4.03 mmol) . The reaction mixture was stirred at 20 C for 1 h. The reaction mixture was adjusted pH to 3-4 by 2 M HCI, filtered, and the solid was washed with water (50 mL), solved into DCM, dried over sodium sulfate and evaporated in vacuo to give the crude product. The crude product was washed with petrol ether/EtOAc/DCM (10/1/1) to afford the target product (E)-N-(1-(4-chlorophenyl)cyclopropyl)-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)acrylamide (685 mg, 1.007 mmol, 100 %)) as a yellow soild.
According to the analysis of related databases, 1009102-44-6, the application of this compound in the production field has become more and more popular.
