실험 절차
A solution of tert-butyl (2-chloro-5-cyano-3-(morpholinomethyl)phenyl)carbamate (45 mg, 0.128 mmol) in a mixture of DCM (2 mL) and TFA (2 mL) was left stirring at RT for 1 hr. The solvent was removed and the residue was dissolved in MeOH and applied onto an SCX column. This was washed with MeOH and the product was eluted with 2N NH3 in MeOH. The solvent was removed to leave 3-amino-4-chloro-5-(morpholinomethyl)benzonitrile (32 mg, 100% yield).
