Reaction Steps

To a solution (±)-ethyl 2-(7-bromo-1′-(2-adamantylcarbamoyl)-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)propanoate (63 mg, 0.122 mmol) in anhydrous MeOH (1 mL) was added LiOH.H2O (10 mg, 0.244 mmol) in H2O (0.1 mL). The reaction mixture was stirred at rt overnight. The mixture was concentrated to give crude product, which was purified by preparative TLC to afford 2-(7-bromo-1′-((2-adamantyl)carbamoyl)-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)propanoic acid. 1H NMR: (400 MHz, CDCl3): δ=1.04 (s, 3H), 1.21 (s, 3H), 1.34-1.43 (m, 2H), 1.60-1.71 (m, 3H), 1.76-2.08 (m, 13H), 2.29-2.40 (m, 1H), 2.51-2.61 (m, 1H), 2.99-3.27 (m, 3H), 3.89 (m, 2H), 4.02-4.14 (m, 2H), 7.01 (m, 1H), 7.21-7.33 (m, 2H).
