Potassium Hydroxide → AKOS BB-8750

Participants

Reaction Steps

A mixture of (adamantan-1-yloxy)-acetic acid ethyl ester (A. F. Noels et al. Tetrahedron, 1982, 38, 2733) (7.29 g, 29 mmol) and potassium hydroxide (2.60 g, 46 mmol) in water-ethanol (1:2 mixture, 180 ml) was heated at reflux for 2 h. The mixture was cooled, then concentrated in vacuum and acidified with concentrated hydrochloric acid. The resultant white precipitate was dissolved in ethyl acetate (200 ml). The solution was washed with brine (2×200 ml), dried (MgSO4) and the solvent was evaporated to afford white crystalline solid (5.85 g 92%). 1H NMR (300 MHz, CDCl3) 4.08 (2H, s), 2.20-1.58 (15H, m).
