Procedure
To a suspension of 5-Amino-indan-1-one (commercially available, 100 mg, 0.679 mmol, 1 eq.) in a 2:1 v/v mixture of EtOAc/H2O (6 mL) is added NaHCO3 (114 mg, 1.36 mmol, 2 eq.). The resulting mixture is cooled to 0° C. followed by the addition of methyl chloroformate (0.052 mL, 0.679 mmol, 1 eq.). After stirring at 0° C. for 15 min., the reaction is warmed to 25° C. and stirred for 12 h. The reaction is diluted with EtOAc and sequentially washed with 1 N HCl (aq) and saturated aqueous NaCl. The resulting organic solution is dried over Na2SO4 and concentrated to give (1-Oxo-indan-5-yl)-carbamic acid methyl ester as a tan solid (124 mg, 89% yield). [MS: (ES+) 206.1 (M+1)+].
