Reaction Steps

To a stirred solution of 4-[4-(2-hydroxy-ethylamino)-6-methoxy-[1,3,5]triazin-2-ylamino]-piperidine-1-carboxylic acid tert-butyl ester (1.00 g, 2.7 mmol, 1.0 equiv) in ethanol (30 mL) was added 4 M HCl in dioxane (3.40 mL, 13.6 mmol, 5.0 equiv) drop by drop. The reaction mixture was subsequently stirred at rt for 72 h and at 80° C. for 2 h. It was then cooled down to rt, poured into ice water and the pH was adjusted to 9-10 by addition of a sat. solution of potassium carbonate. The solution was extracted six times with a mixture of dichloromethane/isopropanol (4:1). The combined organic layers were concentrated by evaporation under reduced pressure to yield 0.60 g (83%) of the title compound as light yellow oil. MS (ISP): 269.2 [M+H]+.
