Operation in experiment
90%
With acetic acid; In water; at 90℃; for 7h;Green chemistry;
General procedure: The mixture of isatin (1 mmol), 3-amino-1-phenyl-1H-pyrazol-5(4H)-one (1 mmol), 1,2-diarylethan-1-one, 2,3-dihydroinden-1-one (1 mmol) or 3,4-dihydronaphthalen-1(2H)-one (1 mmol), H2O (6 mL), HOAc (2 mL) was put in a reaction flask under 90 C about 5-7 h (monitored by TLC). After completion, the reaction mixture was cooled to room temperature and the products would be isolated out at same time. Then, compound 4 was recrystallized from DMF, however, the pure products of 6 and 8 were filtered from water, dried, without further recrystallization.
