실험 절차

4-cyanobenzylamine hydrochloride (EX-59A) was prepared from 10 g (0.030 moles) of 4{N,N-bis-(tert-butoxycarbonyl)aminomethyl}benzonitrile, prepared following Synthetic Communication, 28(23), 4419-4429 (1998), by stirring it in 4N HCl Dioxane (75 ml). After 3 h, the solution was concentraed in vacuo and triturated with ether. The solid was collected by filtration and vacuum dried to yield 5 g (98%) of EX-59A as a white solid: 1H NMR (DMSO) d 8.68 (br s, 2H), 7.84 (m, 2H), 7.67 (m, 2H), 4.06 (s, 2H); HRMS (EI) calcd for C8H8N2 133.0766, found 133.0807
