These common heterocyclic compound, 630-22-8, name is 2,2-Dimethylpropanethioamide, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Formula: C5H11NS
General procedure: A mixture of 60 (5.4g, 35.0mmol), pyridine (11.4ml, 140mmol), and diethyl bromomalonate (3) (8.84ml, 52.5mmol) in EtOH (15ml) was heated under reflux for 16h. The mixture was concentrated under reduced pressure and H2O was added to the residue. The resulting precipitate was removed by filtration and washed with Et2O to deliver ethyl 2-(2-aminopyrimidin-4-yl)-4-hydroxythiazole-5-carboxylate (5.30g, 19.9mmol, 57% yield) as a tan solid.
The synthetic route of 2,2-Dimethylpropanethioamide has been constantly updated, and we look forward to future research findings.
