Lithium hydroxide, monohydrate → HCID 178451168, compound

Participants

Reaction Steps

1.33 g of ethyl cis-6-(4-tert-butoxycarbonylcyclohexyloxy)nicotinate (3.97 mmol, 1 eq.) are dissolved in 60 mL of a 1/1 mixture of THF/methanol. At 0° C., 0.333 g of lithium hydroxide monohydrate (7.93 mmol; 2 eq.) is added with stirring. After stirring for 16 hours at room temperature, the reaction medium is evaporated and aqueous 6% sulfur dioxide solution is added. The precipitate formed is filtered off and washed with water to give 1.25 g of cis-6-(4-tert-butoxycarbonylcyclohexyloxy)nicotinic acid.
