Formic Acid → 1-{[(Benzyloxy)(formyl)amino]methyl}cyclopentane-1-carboxylic acid

Participants

Reaction Steps

To a cold solution of formic acid (10.3 mL, 0.27 mol) in dichloromethane (40 mL) at 0° C. under a nitrogen atmosphere was added acetic anhydride (4.2 mL, 44.1 mmol). After 1 h, a solution of 1-(benzyloxyamino-methyl)-cyclopentanecarboxylic acid (1.1 g, 4.41 mmol) in dichloromethane (20 mL) was added. The mixture was stirred at room temperature for 18 h and was concentrated in vacuo. Water (100 mL) was added and the mixture was extracted with dichloromethane (100 mL×2). The combined organic extracts were dried (MgSO4) and were evaporated in vacuo to yield the title compound as a pale, yellow oil (1.05 g, 86%). MH+278.
