Vorschrift

Powdered potassium hydroxide (95 mg, 1.68 mmol) was added to a solution of the carbonitrile of example 52 (250 mg, 0.56 mmol) in 2-Methyl-propan-2-ol (10 ml). The mixture was heated at 100° C. for 18 hr before evaporating under reduced pressure. The residue was purified by chromatography on silica gel using methanol and ammonium hydroxide in dichloromethane (5:0.5:95) as eluant to give the title compound (220 mg), as a white solid
