Hydrochloric Acid → HCID 67228737, compound

Participants

Reaction Steps

530 mg (1.30 mmol) of tert-butyl[6-({2-[(tert-butoxycarbonyl)amino]ethyl}amino)-3-propanoylpyridin-2-yl]carbamate (Example 24A) were dissolved in 15 ml of a solution of hydrochloric acid in dioxane (4 M), and the mixture was stirred at RT for 20 h. After the reaction had gone to completion, the reaction mixture was diluted with diethyl ether (100 ml), and the precipitate was filtered off, washed with diethyl ether (100 ml) and dried. This gave 290 mg (91% of theory) of the product as a solid.
