Analyzing the synthesis route of 2879-20-1

With the synthetic route has been constantly updated, we look forward to future research findings about 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,belong benzodioxans compound

As a common heterocyclic compound, it belong benzodioxans compound,1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,2879-20-1,Molecular formula: C10H10O3,mainly used in chemical industry, its synthesis route is as follows.,2879-20-1

A solution of 1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)ethanone (XV) (11 mmol), dimethylamine hydrochloride (14 mmol), paraformaldehyde (16 mmol) and 12 N HCl (2 drops) in ethanol (5 mL) was refluxed overnight. The solution was cooled to room temperature and the ethanol was evaporated under vacuum. The residue was treated with ethyl acetate, heated slightly and sonicated to disperse into fine particles. The solids were filtered and dried at room temperature to produce 1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-3-(dimethylamino)propan-1-one (XVI) as a white solid, (82% yield), 1H NMR (CDCl3, 400 MHz): delta ppm 2.77 (s, 6H), 3.41 (m, 2H), 3.56 (m, 2H), 4.25 (m, 4H), 6.85 (m, 1H), 7.45 (m, 2H).

With the synthetic route has been constantly updated, we look forward to future research findings about 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,belong benzodioxans compound
