Versuchsvorschrift
A mixture of 5-[2-acetoxymethyl-3-(6-tert-butyl-1-oxo-1H-phthalazin-2-yl)-phenyl]-1-methyl-1H-pyrrole-2-carboxylic acid methyl ester (237 mg, 0.486 mmol) in saturated NH3/MeOH (20 mL) was stirred at room temperature for 48 h. The mixture was evaporated to dryness to give 5-[3-(6-tert-butyl-1-oxo-1H-phthalazin-2-yl)-2-hydroxymethyl-phenyl]-1-methyl-1H-pyrrole-2-carboxylic acid methyl ester (150 mg, yield 68%) as a yellow solid. LC-MS calcd for C26H27N3O4 (m/e) 445.20, obsd 913 [2M+Na]+.
