As a common heterocyclic compound, it belongs to benzodioxans compound, name is 2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid, and cas is 4442-54-0, its synthesis route is as follows.,4442-54-0
1. Preparation of ethyl 2-[1-[4-(2,3-dihydrobenzo[b][1,4]dioxin-6-carboxamido)benzyl]-1H-indazol-3-yl]acetate 2,3-Dihydrobenzo[b][1,4]dioxin-6-carboxylic acid (154 mg, 0.85 mmol) was dissolved in dichloromethane (15 mL) and N,N-dimethylformamide (0.10 mL), and in an ice bath, oxalic chloride (162 mg, 1.28 mmol) was added dropwise slowly. Upon completion of the dropwise addition, it was moved to react at room temperature for 3 hours, concentrated under reduce pressure to obtain 2,3-dihydrobenzo[b][1,4]dioxin-6-formyl chloride as a white solid.
With the complex challenges of chemical substances, we look forward to future research findings about 4442-54-0,belong benzodioxans compound
