2-Aminoadamantane → HCID 25065228, compound

Participants

Reaction Steps

A solution of 2-aminoadamantane (123 mg, 0.66 mmol), CDI (107 mg, 0.66 mmol), DIEA (232 mg, 0.18 mmol) was stirred at 0° C. for 1 h. Then (±)-ethyl 2-(6-chloro-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)acetate (180 mg, 0.60 mmol) was added to the solution and the mixture was stirred at rt overnight. The solvent was removed and the residue was purified by preparative TLC to give (±)-ethyl 2-(1′-((2-adamantyl)carbamoyl)-6-chloro-2,3-dihydrospiro[indene-1,4′-piperidine]-3-yl)acetate (250 mg, 86%). LC-MS Method 6 tR=1.492 min, m/z=485.2; 1H NMR (CDCl3): δ=1.29 (t, 3H), 1.56-1.66 (m, 4H), 1.66-1.80 (m, 6H), 1.85 (m, 5H), 1.93 (m, 2H), 2.04-2.16 (m, 1H), 2.37-2.49 (m, 1H), 2.56-2.65 (m, 1H), 2.88-2.92 (m, 1H), 3.00-3.20 (m, 2H), 3.55-3.66 (m, 1H), 3.81-3.90 (m, 1H), 3.90-4.00 (m, 2H), 4.20 (q, 2H), 5.26-5.50 (m, 3H), 7.07-7.14 (m, 2H), 7.19 (m, 1H).
