(2R)-4-[(9H-Fluoren-9-ylmethoxy)carbonyl]-2-methylpiperazin-1-ium chloride
Abstract
The synthesis of the title salt, C20H23N2O2+·Cl−, was carried out with a precursor of known absolute configuration (R) and the X-ray analysis confirmed that the product retained the absolute configuration. In the crystal, the dominant packing motif is a chain running along [010] generated by N—H...Cl hydrogen bonding. C—H...O and C—H...Cl interactions are also observed.
