Participants

Reaction Steps

To a solution of 41.6 mg (0.091 mmol) ethyl 2- fluoro-4-[[(5,6-dihydro-5,5-dimethyl-8- (4-methylphenyl)-2-naphthalenyl)carbonyl]amino]-benzoate (Compound 40) in 2.0 ml EtOH and 2.0 ml of THF was added 40.0 mg NaOH (1.00 mmol, 1.0 ml of a 1M aqueous solution). After stirring at room temperature for overnight, the reaction was quenched by the addition of 10% HCl. Extraction with EtOAc, and drying of the organic layers over MgSO4, provided a solid after removal of the solvent under reduced pressure. Crystallization from CH3CN afforded the title compound as a pale-yellow solid. 1H NMR (d6-acetone): δ 9.84 (1H, s), 7.94-7.83 (3H, m), 7.64 (1H, dd, J=2.0 Hz), 7.53 (2H, d, J=8.1 Hz), 7.23 (4H, s), 6.04 (1H, t, J=4.7 Hz), 2.38 (2H, d, J=4.7 Hz), 2.36 (3H, s), 1.35 (6H, s).
