Lithium hydroxide, monohydrate → 6-(Adamantan-1-ylmethoxy)-5-cyclopropylnicotinic acid

Participants

Reaction Steps

A mixture of methyl 6-(adamantan-1-ylmethoxy)-5-cyclopropylnicotinate (1.17 g, 3.43 mmol) and lithium hydroxide monohydrate (0.58 g, 13.70 mmol) in tetrahydrofuran (60 mL) and water (10 mL) was refluxed for 2 h. The reaction mixture was cooled to ambient temperature and diluted with ethyl acetate (100 mL); washed with 1 M aqueous hydrochloric acid (80 mL) and brine (80 mL); dried over anhydrous sodium sulfate; filtered and concentrated in vacuo to afford the title compound which was used without further characterization. MS (ES+) m/z: 328.2 (M+H).
