Participants

Reaction Steps

95% H2SO4 (28 μL, 0.52 mmol) was added to the suspension of 4,6-bis(propylamino)-1,3,5-triazin-2-ol (CLXXVIII) (110 mg, 0.52 mmol) in 1,4-dioxane (2 mL). The mixture was stirred for 30 min at room temperature. The resultant precipitate were filtered, washed with Et2O and dried to afford 4,6-bis(propylamino)-1,3,5-triazin-2-ol hydrogen sulfate (CLXXIX) in quantitative yield. 400 MHz 1H NMR (CD3OD+CF3COOD, ppm) 3.35-3.45 (3.2H, m), 3.22-3.27 (0.8H, m), 1.58-1.70 (4H, m), 0.91-1.0 (6H, m). ESI-MS (m/z): 212 [M+H]+. Major Fragments (M+H) 170, 128, 86.
