With ethanol; tin(ll) chloride; In tetrahydrofuran; for 0.5h;Heating / reflux; | Tin chloride (88.6 g, 392 mmol) inEtOH (50mL) was refluxed and the nitrobenzoate from step A (24.1 g, 78.4 mmol) in 1 :1 THF :EtOH (100mL) was added dropwise. The reaction mixture was refluxed for 30 minutes then cooled to 0 C. The resulting solution was basified to pH 8-9 with aq.Na2C03. The aqueous layer was extracted three times with EtOAc (700 mL) and the combined extracts were washed with saturatedNaHC03 then brine. The organics were dried over Na2SO4 and concentrated to afford the desired aniline which was used without further purification. | |
With tin(ll) chloride; In tetrahydrofuran; ethanol; for 0.5h;Heating / reflux; | Step B: Tin chloride (88.6 g, 392 mmol) in EtOH (50 mL) was refluxed and the nitrobenzoate from stepA (24.1 g, 78.4 mmol) in 1:1 THF:EtOH (100 mL) was added dropwise. The reaction mixture wasrefluxed for 30 min then cooled to 0 C. The resulting solution was basified to pH 8-9 with aq. Na2CO3.The aqueous layer was extracted three times with EtOAc (700 mL) and the combined extracts werewashed with saturated NaHCOs then brine. The organics were dried over Na2SC>4 and concentrated toafford the crude aniline which was used without further purification. | |
Step B: Nitro Reduction; Tin chloride (88.6 g, 392 mmol) in EtOH (50 mL) was refluxed and the nitrobenzoate from step A (24.1 g, 78.4 mmol) in 1:1 THF:EtOH (100 mL).was added dropwise. The reaction mixture was refluxed for 30 minutes then cooled to 0C. The resulting solution was basified to pH 8-9 with aq. Na2C03. The aqueous layer was extracted three times with EtOAc (700 mL) and the combined extracts were washed with saturated NaHC03 then brine. The organics were dried over Na2S04 and concentrated to afford 21.7 g of the crude aniline which was used without further purification. |
Step B: Tin chloride (88.6 g, 392 mmol) in ETOH (50 mL) was refluxed and a 1: 1 THF : ETOH (100 mL) solution of the nitrobenzoate from step A (24.1 g, 78.4 mmol) was added dropwise. The reaction mixture was refluxed for 30 minutes then cooled to 0C. The solution was basified to pH 8-9 with aq. NA2CO3. The aqueous layer was extracted with EtOAc (3 x 700 mL). The combined organics were washed with saturated NAHC03 then brine. The organics were dried over NA2S04 AND concentrated affording the crude aniline. LCMS [M + H] = 278.0 |

With pyridine; In dichloromethane; at 0 - 20℃; | To a0 C solution of aniline from step B (21.7 g, 78.3 mmol) in 3: 1CECl2 : pyridine (75mL) was added methanesulfonyl chloride (6.36mL, 82.2 mmol). The ice bath was removed after 15 minutes and the solution was. stirred overnight at rt. The reaction mixture was extracted several times with INHC1. <Desc/Clms Page number 47>The organic phase was dried, concentrated, and chromatographed (1: 1 EtOAc: Hex) to afford the desired sulfonamide as a white solid. | |
With pyridine; In dichloromethane; at 0 - 20℃; | Step C: To a 0C solution of aniline from step B (21.7 g, 78.3 mmol) in 3:1 DCM:pyridine (75 mL) wasadded methanesulfonyl chloride (6.36 mL, 82.2 mmol). The ice bath was removed after 15 min and thesolution was stirred overnight at rt. The reaction mixture was extracted several times with IN HC1. Theorganic phase was dried, concentrated, and cliromatographed (1:1 EtOAc:Hex) to afford the desiredsulfonamide as a white solid. | |
With pyridine; In dichloromethane; at 0 - 20℃; | Step C: Mesylation; To a 0 C solution of aniline from step B (21.7 g, 78.3 mmol) in 3:1 1 CH2Cl2: pyridine (75 mL) was added methanesulfonyl chloride (6.36 mL, 82.2 mmol). The ice bath was removed after 15 min and the solution was stirred overnight at rt. The reaction mixture was extracted several times with IN HCI. The organic phase was dried, concentrated, and chromatographed (1:1 EtOAc:Hex) to afford 25.2 g of the desired sulfonamide as a white solid. |
With pyridine; In dichloromethane; at 0 - 20℃; | Step C: To a 0C solution of the aniline from step B (21.7 g, 78.3 mmol) in 3: 1 CH2CIZ : PYRIDINE (75 mL) was added methanesulfonyl chloride (6.36 ML, 82.2 mmol). The ice bath was removed after 15 minutes and the reaction mixture was stirred overnight at room temperature. The reaction mixture was diluted with EtOAc (200 mL), washed 2x IN HC1, and dried over MGSO4. The solvent was removed in vacuo and the residue was purified by silica gel chromatography (1 : 1 EtOAc/Hexanes) to provide he sulfonamide. LCMS [M+] 355. 8.
