With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.111769-27-8,(R)-Tetrahydrofuran-3-amine 4-methylbenzenesulfonate,as a common compound, the synthetic route is as follows.

To a solution of (2,6-dimethylpyridin-4-yl)methyl 4-nitrophenyl carbonate (Intermediate 2;235 mg, 0.78 mmol) in DMF (5 mL) was added DIPEA (400 muL, 2.3 mmol), (R)- tetrahydrofuran-3 -amine toluenesulfonate (221 mg, 0.85 mmol) and DMAP (10 mg, catalytic). The reaction mixture was stirred overnight and then concentrated in vacuo. The residue was dissolved in EtOAc (25 mL), washed with IM aq Na2CO3 solution (5 x 25 mL), dried (MgSO4) and concentrated in vacuo. The residue was dissolved in DCM (5 mL) and treated with 2M HCl in Et2O (0.5 mL, 1.0 mmol) to give a precipitate. The – -solvent was removed by decantation and the precipitate was dried in vacuo to give (2,6- dimethylpyridin-4-yl)methyl (3R)-tetrahydrofuran-3-ylcarbamate hydrochloride (102 mg, 46%) as a white solid.Analytical HPLC: purity 99.3% (System A, Rtau = 3.03 min); Analytical LCMS: purity 100% (System E, Rtau = 4.59 min), ES+: 251.4 [MH]+; HRMS calcd for Ci3Hi8N2O3: 250.1317, found 250.1330.
