Yield:597563-17-2 87.6%

Reaction Conditions:

with triethylamine in dichloromethane at 0 - 20; for 4 h;

Steps:

1 Step 1:

To a cooled (0°C) suspension of l-(3-bromophenyl)cyclopropan-l-amine hydrochloride (2.0 g, 8.05 mmol) in dry DCM (15 mL) were added di-tert-butyl dicarbonate (1.76 g, 8.05 mmol) and triethylamine (977.02 mg, 9.66 mmol). The reaction mixture was stirred at room temperature for 4h. Water (5 mL) was added, the organic phase was separated and washed with 5% aq. HC1, water, dried over sodium sulfate, filtered, and concentrated to give tert-butyl N-[l-(3-bromophenyl)cyclopropyl]carbamate (2.2 g, 7.05 mmol, 87.6% yield) as white solid.
