Procedure
NaOH (19M; 1.0 mL) was added to a solution of 1-hydroxy-4-methoxyindan-1-yl-carboxylic acid ethyl ester (0.90 g; 3.8 mmol; from step (ii) above) in EtOH (20 mL) and the solution was stirred for 30 minutes. Brine (40 mL) was added and the mixture was washed with EtOAc, cautiously made acidic to pH 2 (HCl; 2M), and the aqueous solution was extracted with EtOAc. The organic layer was washed with brine, dried (Na2SO4) and concentrated, yielding 0.70 g (88%) of the sub-title substance.
