Reaction Conditions

Reaction Steps

To a solution of allyl-[2-(4-amino-phenyl)ethyl]-carbamic acid tert-butyl ester (1.86 g, 6.74 mmol) in pyridine (25 ml) at 0° C. was added 4-isopropyl-benzenesulfonyl chloride (1.47 g, 6.74 mmol) and the mixture was stirred at 0° C. for 1 h. After concentration in vacuo the residue was partitioned between ethyl acetate and saturated aqueous NaHCO3. The organic layer was washed with water, dried over MgSO4, filtered and the solvent evaporated under reduced pressure. The residue was purified by column chromatography (n-heptane/ethyl acetate, 2/1) to give the product as a yellow resin (1.35 g, 43.6 mmol).
