Reaction Steps

A mixture of (E)-3-(1′-cyclopentyl-4-oxospiro[chroman-2,3′-piperidine]-6-yl)-N-hydroxyacrylamide hydrochloride (80 mg, 0.197 mmol), hydroxylamine hydrochloride (27.3 mg, 0.393 mmol) and pyridine (0.032 ml, 0.393 mmol) in ethanol (2 ml) was heated at 80° C. The solvent was removed in vacuo and the crude was purified by preparative LC-MS to give the title compound (9.56 mg) as trifluoroacetate
