Reaction Steps

((S)-6-Bromo-1,2,3,4-tetrahydro-naphthalen-2-yl)-carbamic acid tert-butyl ester (12.2 g, 37.4 mmol) was dissolved in N,N-dimethylformamide (1000 ml). Sodium hydride (50% in oil) (1.975 g, 41.14 mmol) was added and the mixture was stirred for 15 minutes at room temperature. Propyl bromide (3.74 ml, 41.14 mmol) was added and the reaction mixture was stirred at room temperature over night. The reaction mixture was poured into a mixture of ice and H2O (400 ml) and extracted twice with 200 ml of diethyl ether. The organic layer was dried over magnesium sulfate, filtered, and evaporated to dryness to yield 14.4 g of crude product. The crude product was purified by chromatography on silica gel using cyclohexane/ethyl acetate (95:5) as eluent, yielding the title compound (10.5 g, 76%).
