Procedure

A reaction tube was charged with a suspension of 1 (270 mg, 0.9 mmol) and Lindlar catalyst (192 mg, 10 mol %) in methanol (5 mL), and was then placed on a Parr shaker. The was reaction pressurized with H2 (60 psi) and maintained for 1 h. The reaction was filtered through Celite and the remained solids were washed with methanol. The combined organics were concentrated to give 2 as a brown semi-solid which was carried forward without further purification LCMS m/z 273.3 (MH+), tR=1.56 min.
