| Product | 4-Amino-2-[(2-aminoethyl)amino]-1,3-thiazol-5-carbonitrile dihydrochloride | HCID 86651624 | — |
Reaction Steps
2.18 g (7.7 mmol) of tert-butyl {2-[(4-amino-5-cyano-1,3-thiazol-2-yl)amino]ethyl}carbamate (Example 7A) in 100 ml of 4N hydrogen chloride in dioxane were stirred at RT for 30 min. The reaction mixture was concentrated. This gave 2 g (100% of theory) of the product as a solid.
