590 mg (1.49 mmol) ethyl 6-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-pyrimidine-4-carboxylate, 20 mL ethanol, 1 mL water and 1 mL (4.0 mmol) of a 4M NaOH solution were stirred for 2 h at RT. The reaction mixture was diluted with water until the precipitate had dissolved. 1 mL of a 4M hydrochloric acid solution were added and the ethanol was eliminated i. vac. The reaction mixture was stirred for 30 min at RT, the precipitate was suction filtered and dried at 50° C. in the CAD.
