3663-80-7, 2,3-Dihydrobenzo[b][1,4]dioxine-2-carboxylic acid is a benzodioxans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,3663-80-7
1. Preparation of ethyl 2-[1-[4-(2,3-dihydrobenzo[b][1,4]dioxin-2-carboxamido)benzyl]-1H-indazol-3-yl]acetate 2,3-Dihydrobenzo[b][1,4]dioxin-2-carboxylic acid (145 mg, 0.80 mmol) was dissolved in dichloromethane (15 mL) and N,N-dimethylformamide (0.10 mL), and in an ice bath, oxalic chloride (153 mg, 1.21 mmol) was added dropwise slowly. Upon completion of the dropwise addition, it was moved to react at room temperature for 3 hours, and concentrated under reduce pressure to obtain 2,3-dihydrobenzo[b][1,4]dioxin-2-formyl chloride as a white solid.
As the paragraph descriping shows that 3663-80-7 is playing an increasingly important role.
