Versuchsvorschrift
A solution of the title compound of Step (A) (6.00 g; 30 mmol) in 50 ml of EtOH was saturated with anhydrous NH3. An exothermic reaction was observed. After stirring the reaction mixture 60 hr at room temperature, the volatiles were removed in vacuo and the solid residue was taken up in a minimal amount of hot ethyl acetate. A small amount of insoluble material was filtered off and hexane was added to the filtrate until slightly turbid. After cooling to room temperature and standing several hr, the crystals were filtered and dried to afford 4.68 g (91%) of the title compound of this step as a colorless crystalline solid.
