Lithium hydroxide, monohydrate → HCID 67479165, compound

Participants

Reaction Steps

To a solution of 6 (353.7 mg, 0.660 mmol) in a mixture of dioxane (3302 μL) and water (3302 μL) was added lithium hydroxide monohydrate (27.7 mg, 0.660 mmol). The reaction was stirred at room temperature for 72 hours. The reaction mixture was then extracted with DCM. The aqueous layer was diluted with 1N HCl. A precipitate was formed and separated by filtration to give 7 as a light purple solid. 1H NMR (400 MHz, CDCl3 with 1% TFA) δ ppm 1.50-1.70 (m, 1H) 1.83-2.00 (m, 2H) 2.00-2.13 (m, 1H) 2.43-2.56 (m, 1H) 3.23-3.30 (m, 1H) 3.50-3.61 (m, 1H) 3.78-3.92 (m, 10H) 4.01 (d, J=14.08 Hz, 1H) 4.45 (d, J=10.76 Hz, 2H) 6.25-6.37 (m, 1H) 6.86 (s, 2H) 7.38-7.51 (m, 2H) 7.69 (d, J=7.43 Hz, 1H) 7.89-7.99 (m, 2H); M+H 522.23432.
