Participants

Reaction Steps

0.894 g of N—(N-BOC-(R)-valyl)-1,2,3,6-tetrahydropyridin-3-ol dissolved in 10 ml of CH2Cl2 are treated with 0.844 g of 4-dimethylaminopyridine and 0.31 g of methanesulfonic acid chlorid (mesylchloride) and stirred for ca. 24 hours, the mixture obtained is treated with 0.1 N HCl and CH2Cl2, the organic phase obtained is washed with H2O and aqueous NaHCO3-solution, the solvent is evaporated and the evaporation residue is dried. 3-Mesyloxy-N—(N-BOC-(R)-valyl)-1,2,3,6-tetrahydropyridine is obtained. 1H-NMR (CDCl3): 6.1-5.85(m,2H,HIV,HV), 4.5(m,1H,NHCHCO), 3.7(s,3H,CH3SO2), 1.2-0.9(m,6H,(CH3)2.
