Procedure
Over a solution of (trans)-2-phenylcyclopropanamine (intermediate A, 1.14 g, 1 eq) in 50 mL of THF, 1.25 g (1.05 eq) of K2CO3 was added and stirred 3 hours at room temperature. After removal of the solvent, CH2Cl2 was added, then washed with a saturated solution of NaHCO3 and brine. The organic layer was extracted, dried with MgSO4 and filtered. The crude was purified by silica gel chromatography (Hexane-MTBE 90:10) affording 1.89 g of tert-butyl(trans)-2-phenylcyclopropylcarbamate. Yield: 95%
