Reaction Conditions

Reaction Steps

A mixture of 1-(benzyloxyimino-methyl)-cycloheptanecarboxylic acid methyl ester (5.2 g, 18 mmol) and lithium hydroxide monohydrate (7.56 g, 180 mmol) in THF (80 mL) and water (40 mL) was stirred at 60° C., for 24 h. The THF was removed in vacuo and the reaction mixture was acidified to pH 4 with 6N aqueous HCl and was extracted with dichloromethane (50 μL×5). The combined organic layers were dried (MgSO4) and were evaporated in vacuo to yield the title compound (4.44 g, 90%). MH+276.
