Procedure

3-Bromo-benzylamine HCl salt (0.75 g) was dissolved in 10 mL 15% IPA in CH2Cl2. 7 drops of 10N Sodium Hydroxide (NaOH) was added and stirred for 3 minutes. To the reaction mixture, 5 mL of dH2O was added and stirred for 5 minutes. The IPA/CH2Cl2 layer was extracted. The aqueous layer was rinsed with 10 mL 15% IPA in CH2Cl2. All organic layers were added together and concentrated under vacuum. MS (ESI+) for C7H8BrN m/z 186.3 (M+H)+
