Diphenyl N-Cyanocarbonimidate → HCID 178512234, compound

Participants

Reaction Steps

The single enantiomer was then BOC-protected, the nitro group reduced by treatment with H2/Pd and the primary aniline treated with diphenyl cyanocarbonimidate (slight excess) in 20 mL of isopropanol with stirring at ambient temperature overnight. The solid was filtered, washed with isopropanol and ether and dried to give phenyl (7S)—N′-cyano-N-(7-amino-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)carbamimidate, as a white solid in high yield (from the single enantiomer via transamination).
