Procedure

To a stirred solution of methyl 2-(1′-((2-adamantyl)carbamoyl)-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)acetate isomer A (2.0 mg, 5 μmol) in water (0.25 mL), THF (0.25 mL) and methanol (0.5 mL) was added LiOH.H2O (10 mg, 0.23 mmol). The mixture was stirred overnight at rt. The mixture was diluted with 5% aq HCl (10 mL) and extracted with EtOAc (2×40 mL). The combined organic extracts were dried over Na2SO4 and concentrated to leave crude 2-(1′-((2-adamantyl)carbamoyl)-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)acetic acid isomer A (3 mg, quant) as an oil. 1H NMR (CDCl3) δ=2.49 (m, 1H), 2.63 (m, 1H), 3.00 (m, 1H), 3.1 (1H), 3.65 (1H), 3.92 (1H), 4.02 (2H); LC-MS (3 min) tR=1.90 min, m/z=423.
