960.3 g | With sodium carbonate; In water; ethyl acetate; at 40 - 90℃; for 4h; | Intermediate 33 (1860 g, 4.23 mol, 1.0 eq.) was suspended in water (5 L) and the slurry was heated to an internal temperature of 40 C. Solid Na2CO3 (1460 g, 13.77 mol, 3.25 eq.) was then added in small portions over a period of 20 minutes. Foaming resulted on initial addition, so EtOAc (0.2 L) was added to collapse the foam and suppress any further foaming. Once addition was complete, the brown suspension was heated to 90 C. over 40 minutes, then stirred at 90 C. for 90 minutes, then cooled to 40 C. over 90 minutes. EtOAc (1.5 L) was added, followed by addition of aqueous concentrated HCl via dropping funnel (0.7 L), resulting in vigorous evolution of CO2 gas and evaporation of most of the EtOAc. Further EtOAc (1 L) was added to wash the foaming product from the condenser and the walls of the reactor, then additional EtOAc (0.3 L) was added and the thick slurry was stirred at RT overnight. The slurry was then heated to 40 C. and further aqueous concentrated HCl was added via dropping funnel with vigorous stirring over 45 minutes, resulting in CO2 gas evolution, evaporation of most of the EtOAc and formation of a solid. Stirring was ceased, and the solid floated to the top of the aqueous mixture (pH 1). The majority of the aqueous layer was separated (ca. 5 L) and then 2-MeTHF (5 L) was added. The clear aqueous layer was then removed, and the organic layer diluted to 10 L with additional 2-MeTHF, and warmed to 50 C. to give a dark orange solution.The organic layer was then washed with 1 M HCl (0.5 L), evaporated, and azeotroped with toluene to afford the title compound as a tan coloured solid (960.3 g). LCMS (Method 4): Rt 2.73 min, m/z 227, 229 [M-H] 1H NMR (300 MHz, DMSO): delta 10.26 (1H, d, J=0.8 Hz), 8.20 (1H, d, J=1.5 Hz), 8.08-8.04 (1H, m), 7.95 (1H, d, J=8.0 Hz). |
