Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Diethyl (ethoxymethylene)malonate | HCID 6871 | — |
| Reactant | 3,4-Dihydro-2H-pyrimido[2,1-b][1,3]benzothiazol-7-amine | HCID 13338584 | — |
| Product | HCID 20446961 | HCID 20446961 | 96% |
Reaction Steps
A mixture of 5.13 parts of 3,4-dihydro-2H-pyrimido[2,1-b]benzothiazol-7-amine and 6.5 parts of diethyl 2-(ethoxymethylene)propanedioate is stirred for 30 minutes at 100°-110° C. The product solidifies on triturating in 1,1'-oxybisethane, yielding 9 parts (96%) of diethyl 2-[(3,4-dihydro-2H-pyrimido[2,1-b]benzothiazol-7-yl)aminomethylene]propanedioate.
