実験手順

Starting from dimethyl trans-1,2-cyclopropanedicarboxylate, trans-N-tert-butyloxycarbonyl-1,2-cyclopropanediamin hydrochloride may be prepared and purified analogously to cis-N-tert-butyloxycarbonyl-1,2-cyclopropanediamin hydrochloride (see 58.4). M.p: 200-202° C.

後処理

  1. custommay be prepared
  2. custompurified analogously to cis-N-tert-butyloxycarbonyl-1,2-cyclopropanediamin hydrochloride (see 58.4)
