Reaction Steps
To (S)-5-bromo-2,3-dihydro-1H-inden-2-amine((1R,4S)-7,7-dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonate (13.95 mmol, 6.2 g) in EtOAc (93 mL)/Water (93 mL) was added benzyl carbonochloridate (15.35 mmol, 2.62 g) dropwise at 0° C. under an argon atmosphere. The reaction was left to stir for 18 hrs. The aqueous layer was removed before washing the organic with brine. The organics were dried over MgSO4 before filtering and removing the solvent in vacuo to give the title compound as a white solid (4.8 g, 99%). 1H NMR (400 MHz, CDCl3) δ 2.79 (m, 2H), 3.25 (m, 2H), 4.53 (d, 1H), 4.93 (brs, 1H), 5.10 (s, 2H), 7.08 (d, 1H) 7.31 (m, 7H).
