HPLC of Formula: C8H6ClNO,The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research.
EXAMPLE 1a Preparation of intermediate E/Z-6-chloro-3-(3-chloro-benzylidene)-1,3-dihydro-indol-2-one To the mixture of 6-chlorooxindole (16.2 g, 92 mmol) (Crescent) and 3-chloro-benzaldehyde (12.9 g, 92 mmol) (Aldrich) in methanol (109 mL) was added pyrrolidine (6.55 g, 92 mmol) (Aldrich) dropwise. The mixture was then heated at 70 C. for 3 h. After cooled to 4 C., the mixture was filtered and resulting precipitate was collected, dried to give a mixture of E/Z-6-chloro-3-(3-chloro-benzylidene)-1,3-dihydro-indol-2-one as a bright yellow solid (Yield 25.2 g, 95%).
Hope you enjoy the show about 56341-37-8.
