Reaction Steps

A mixture of Example 65B (0.120 g, 0.55 mmol) and salcomine (0.022 g, 0.06 mmol) in methanol (30 mL) was treated with oxygen over 18 hours and concentrated. The concentrate was purified by flash column chromatography on silica gel to provide 0.112 g of the desired product. MS (ESI(+)) m/z 232 (M+2) and 248 (M+NH4)+;
