Reaction Steps
A vial, equipped with a flea stir bar, was charged with methanesulfonyl chloride (4.5 μL, 58 μmol), DIEA (15 μL, 90 μmol) and CH2Cl2 (1 mL). A solution of N-(2-adamantyl)-2,3-dihydro-1H-spiro[isoquinoline-4,4′-piperidine]-1′-carboxamide (25 mg, 53 μmol) in CH2Cl2 (1 mL) was added and the mixture was stirred overnight. A 10-mL Chem-Elut cartridge was wetted with 5% aq HCl (6 mL) and allowed to stand for 5 min. The reaction mixture was applied to the cartridge and eluted with ether (20 mL). The eluate was evaporated to dryness and the residue was purified by preparative HPLC to afford N-(2-adamantyl)-2-(methylsulfonyl)-2,3-dihydro-1H-spiro[isoquinoline-4,4′-piperidine]-1′-carboxamide (8 mg, 33%). LC-MS Method 1 tR=1.89 min, =458; 1H NMR (CDCl3) δ=1.60-2.15 (18H), 2.92 (s, 3H), 3.13 (m, 2H), 3.51 (s, 2H), 3.90 (d, 2H), 3.99 (s, 1H), 4.45 (s, 2H), 4.88 (1H), 7.05-7.40 (4H).
