Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 924304-73-4, name is 4-Chloroisoindoline hydrochloride, This compound has unique chemical properties. The synthetic route is as follows., Formula: C8H9Cl2N
Step 3: Synthesis of (2Jff,65>,13a5′,14ai?,16a5rZ)-ethyI 6-(tert-butoxycarbonylamino)-2-(4- chloroisoindoline-2~carbonyloxy)-5,16-dioxo-2,3,5,6,7,8,9,ll,13a,14,14a,15,16,16a- tetradecahydro-lH-cyclopropa(e)pyrrolo[2,l-i][l,7,10joxadiazacyclopentadecine-14a- carboxylate[0472] (2R,6S, 13aS, 14aR, 16aS,Z)-ethyl 6-(tert-butoxycarbonylamino)-2-hydroxy- 5,16-dioxo~2,3,5,6,7,8,9,l l,13a,14,14a,15,16,16a4etradecahydro-1H- cyclopropa(e)pyrrolo[2,l-/][l,7,10]oxadiazacyciopentadecine-14a-carboxylate (0.30 g, 0.61 mmol) in toluene (5 mL) was added lj ‘-carbonyldiimidazole (0.12 g, 0.73 ramol) in one portion. The reaction was stirred at room temperature for 3 hours. To the reaction was then added the N-ethyl-N-isopropylpropan-2-amine (0.53 mL, 3.0 mmol), followed by 4- chloroisoindoline hydrochloride salts (0.15 g, 0.79 mmol). The reaction was stirred at 60 C for 3 hours. The solvent was removed. The residue was partitioned between ethyl acetate (20 mL) and saturated sodium bicarbonate solution. The organic layer was separated and dried over sodium sulfate. After removal of solvent, the residue was purified by chromatography (etaexanerEthyl acetate=l:3) to give (2/?,65,13a5,14aR,16a5’,Z)-ethyI 6-{tert- butoxycarbonylamino)-2-(4-chloroisoindoline-2-carbonyloxy)-5,16-dioxo- 2,3,5,6,7,8,9,11, 13a,14,14a,15,16,16a-tetradecahydro-1H-cyclopropa(phiyrrolo[2,l- /][l,7,10]oxadiazacyclopentadecine-14a-carboxylate as white solid (0.18 g, 86%). MS: Calcd.: 674.3; Found: [M+eta]+ 675.1.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 924304-73-4.
