Conditions

Temperature: 80 °C

Procedure

A suspension of 174 mg (0.4 mmol) of Compound 23 and 111 mg (1.6 mmol) of hydroxylamine hydrochloride in 10 ml of pyridine was stirred for 24 hours over an oil bath of 80° C. Post-treatment and purification were conducted in a similar manner as in Example 21, whereby 159 mg of the title compound were obtained (yield: 88%).
