Versuchsvorschrift

A mixture of o-nitrophenyl cyclopropyl ketone (100 mg, 0.52 mmole) and a catalytic amount of 10% Pd on carbon in methanol is stirred under hydrogen at atmospheric pressure until reaction is complete by TLC. The reaction mixture is filtered and the filtrate is concentrated in vacuo to give a bright yellow oil. The oil is flash chromatographed to give the title product as an off-white crystalline solid, 72 mg (85% yield), identified by 1HNMR.
