The reaction mixture was concentrated under reduced pressure. To the residue was added a saturated aqueous sodium hydrogen carbonate solution and the mixture was extracted with ethyl acetate. The extract was dried and concentrated under reduced pressure to give 3-[(2S,4R)-1-tert-butoxycarbonyl-4-hydroxypyrrolidin-2-ylcarbonyl]thiazolidine (56.3 g, 62%) as a colorless oil.

91% | (1) To a suspension of sodium triacetoxyborohydride (13.68 kg) in toluene (300 L) were added 1-[4-(3-methyl-1-phenyl-1H-pyrazol-5-yl)piperazine acetate (15.00 kg) and 3-[(2S)-1-(1,1-dimethylethyloxycarbonyl)-4-oxopyrrolidin-2-ylcarbonyl] thiazolidine (14.90 kg), and the mixture was stirred at room temperature for 2.5 hrs. Water (90 L) was added dropwise to the reaction mixture and the mixture was stirred for 0.5 hr. The toluene layer was separated, washed successively with 5% aqueous sodium hydrogencarbonate solution (90 L) and water (90 L) and concentrated to dryness under reduced pressure. IPA (224 L) was added to the residue and 48% hydrobromic acid (25.08 kg) was added dropwise at about 80C, and the mixture was refluxed for 2.5 hrs. The reaction mixture was allowed to cool, and stirred at about 60C for 1.5 hrs, at about 40C for 2 hrs, and then at room temperature for 2 hrs. The precipitate was collected by filtration, washed with IPA (30 L) and dried with warm air to give the title compound as a solid (29.76 kg, yield 91%). (2) To the solid (28.00 kg) obtained in (1) was added ethanol (168 L), and the solid was dissolved by heating. The solution was filtered hot. The reaction vessel was washed with ethanol (28 L), and the filtrate and washing were combined. Water (3 L) was added at 67C, and the mixture was allowed to cool and stirred at 49C for 1 hr and then at 20-15C for 1 hr. The precipitate was collected by filtration, washed with ethanol (28 L) and dried with warm air to give the title compound as crystals (25.84 kg, yield 92%). XRD: 5.4, 13.4, 14.4, 22.6, 26.5. |
