N'-(2-methoxyethyl)ethane-1,2-diamine;dihydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 15.5 ml of a 2 N solution of hydrogen chloride in diethyl ether (31 mmol, 10 equivalents) were added to 750 mg of tert-butyl {2-[(2-methoxyethyl)amino]ethyl}carbamate (Example 165A, purity about 90%, 3.1 mmol, 1 equivalent), and the mixture was stirred at RT overnight. The solvent was decanted off, the residue was triturated three times with diethyl ether and the product obtained in this manner was dried under reduced pressure. This gave 482 mg (82% of theory) of the title compound. The solvent was decanted off the residue was triturated three times with diethyl ether the product obtained in this manner was dried under reduced pressure
