Reaction Steps

To a solution of N-(2-adamantyl)-1-oxo-1,3-dihydrospiro[indene-2,3′-piperidine]-1′-carboxamide (3.0 mg, 0.079 mmol) in MeOH (3 mL) was added NaBH4 (12 mg, 0.317 mmol) at 0° C. under nitrogen. The reaction mixture was stirred for 4 h under N2 at rt. The reaction mixture was evaporated to give a residue, which was purified by preparative HPLC to afford N-(2-adamantyl)-1-hydroxy-1,3-dihydrospiro[indene-2,3′-piperidine]-1′-carboxamide (12 mg, 40%). 1HNMR (CD3OD, 400 MHZ): δ=1.51-1.75 (m, 5H), 1.78˜1.81 (m, 4H), 1.82˜2.00 (m, 11H), 2.50 (m, 1H), 3.00 (d, 1H), 3.20 (m, 1H), 3.55 (m, 1H), 3.65 (m, 1H), 3.81 (s, 1H), 4.75 (s, 1H), 7.22 (m, 3H), 7.388 (m, 1H).
