Lithium hydroxide, monohydrate → HCID 43088494, compound

Participants

Reaction Steps

A solution of compound 55g (87 mg, 0.31 mmol), and LiOH.H2O (52 mg, 1.24 mmol) in THF/H2O (2/2 mL) was stirred at room temperature overnight. The resulting mixture was concentrated and diluted with water. The water layer was acidified with 1N aqueous HCl to pH˜6 and extracted with CH2Cl2. The organic solution was dried over Na2SO4 and concentrated to give 55h (82 mg), which was used in the next reaction without further purification. MS m/z (M+H+) 268.0.
