Participants

Reaction Steps

Cbz-Cl (7.2 ml, 21.259 mol, 1.5 eq., 50% solution in toluene) was added at 0° C. to a mixture of 4-(methylamino)piperidin-2-one (1.814 g, 14.173 mmol, 1.0 eq.) and K2CO3 (3.91 g, 28.346 mmol, 2.0 eq.) in THF (50 ml) and the mixture was stirred for 14 hours at RT. After monitoring by TLC, the reaction mixture was diluted with DCM (300 ml), washed with water and saturated NaCl solution (in each case 150 ml), dried over sodium sulfate, concentrated under reduced pressure and purified by column chromatography (Alox, 1% MeOH in DCM). Yield: 27% (1.0 g, 3.82 mmol)
