Pyrrolidine → HCID 21080215, compound

Participants

Reaction Steps

Using analogous procedures to those described in Note [33] immediately above, 1-(tert-butoxycarbonyl)-L-proline was reacted with pyrrolidine to give (2S)-1-(tert-butoxycarbonyl)-2-(pyrrolidin-1-ylcarbonyl)pyrrolidine which was deprotected and reacted with 2-bromoethanol. There was thus obtained the required starting material; NMR Spectrum: (CDCl3) 1.7-2.05 (m, 8H), 2.1-2.3 (m, 1H), 2.42.5 (m, 1H), 2.55-2.7 (m, 1H), 2.8-2.9 (m, 1H), 3.2-3.3 (m, 2H), 3.4-3.7 (m, 5H), 4.1 (br s, 1H); Mass Spectrum: M+H+ 213.
