실험 절차

A mixture of EXAMPLE 138B (1.4 g) and hydrazine (1.548 mL) in ethanol (40 mL) was heated at 70° C. overnight, cooled to room temperature, slurried with CH2Cl2 (200 mL) and the solid removed by filtration. The filtrate was concentrated and chromatographed on silica gel eluting with 100:5:1 ethyl acetate/methanol/NH4OH to give the product.
