Yield:157327-41-8 100%
Reaction Conditions:
in N,N-dimethyl-formamide at 80; for 24 h;
Steps:
24.1 Step 1) 1-(tert-butoxycarbonyl)-3-((dimethylamino)methylene)piperidin-4-one
A mixture of N,N-dimethylformamide dimethyl acetal (18 g, 20 mL, 151 mmol) and l-(tert-butoxycarbonyl)piperidin-4-one (30 g, 151 mmol) in DMF (240 mL) was stirred at 80 °C for 24 h. The mixture was concentrated in vacuo to give the title compound as a yellow solid (38.4 g, 100%). MS (ESI, pos. ion) m/z: 255 [M + H]+.
