Reaction Steps

NaOH (10M, 1 mL) was added to a solution of 7-chloro-1-hydroxytetraline-1-carboxylic acid, ethyl ester (0.8 g; 3.1 mmol; from step (iii) above) in DMSO (20 mL), and the mixture was heated to 100° C. for 3 hours. The resultant mixture was diluted with crushed ice (40 g) and brine (40 mL), and the mixture was extracted with EtOAc. The aqueous layer was acidified to pH 2 with 2M HCl and extracted with EtOAc (2×40 mL). The combined organic layer was dried (Na2SO4) and concentrated. Yield 0.22 mg (30%).
