71.5% | In toluene; at 70℃; for 16h;Large scale; | Into a 50 L reactor, anhydrous toluene (20 L) was added. Compound 3 (6.95 kg, 15.46 mol) was added. Anhydrous methanol (6.26 L, 154.6 mol) was added under stirring. The internal temperature of the reactor was controlled at 70 C. and the feed liquid was stirred for 16 h. Sampling test was performed by TLC (PE:EtOAc=1:1). After completion of the reaction, the reaction solution was concentrated under reduced pressure to give a red brown viscous liquid. The crude product was dissolved in 6 L EtOH and 10 L petroleum ether. The solution was stirred at 13 C. for 30 minutes with a white solid to be precipitated. After stirring for 2 hours, the solution was allowed to stand overnight and filtered, and the solid was washed three times with petroleum ether (5 L) and then dried to give compound 4 as a product (4.2 kg, 11.07 mol), with a yield of 71.5% and purity of 98%. |

---|---|---|
66% | With sodium hydrogencarbonate; In N,N-dimethyl-formamide; at 60℃; for 4h;Inert atmosphere; | Step 1 (Synthesis of 177-4) (0846) Compound 177-1 (3.86 g, 26.36 mmol, 1.0 eq.), 177-2 (10.0 g, 26.36 mmol, 1.0 eq.), 177-3 (4.31 g, 26.36 mmol, 1.0 eq.) were dissolved in anhydrous DMF (100 mL), and at 20 C. was added NaHCO3 (8.86 g, 105.44 mmol, 4.00 eq). After the addition, the reaction mixture was swept with nitrogen for 3 times, the mixture was warmed to 60 C., and stirred for 4 hours. The reaction mixture was cooled to room temperature, and filtered. The filtrate was concentrated under reduced pressure. The residue was dissolved in EtOAc, washed with water (100 mL), and then extracted with EtOAc (100 mL) for 3 times. (0847) The organic phases were washed with saturated brine, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by column chromatograph with an eluent system of DCM/MeOH=20/1, 10/1, to obtain 11 g product as yellow oil, yield: 66%. (0848) LCMS (ESI) m/z: 527.1 [M+H+]. |
