2-Chloro-1,3-dimethylimidazolidinium h... Use and Manufacturing

Step 1HOBt (27.8 mg, 0.206 mmol) in DCM (2 mL) was added to 2-chloro-1, 3-dimethyl- 4, 5-dihydro-1H-imidazol-3-ium hexafluorophosphate (57.4 mg, 0.206 mmol) and triethlyamine (0.029 mL, 0.21 mmol) in DCM (2 mL). The reaction was stirred at rt for overnight. The reaction mixture was filtered to collect 2-((1H-benzo[d][1, 2, 3]triazol-1-yl)oxy)-1, 3-dimethyl-4, 5-dihydro-1H-imidazol-3-ium hexafluorophosphate, , as white solid. MS m/z 232.1(M+). Retention time 0.324 min. This material was used in the next step without further purification.Step 1 : Preparation of (1, 3-dimethylimidazolidin-2-ylidene) isoquinolin-5-ylamine A mixture of 5-aminoisoquinoline (0.3 g, 2.09 mmol) and 2-chloro-1, 3-dimethylimid- azolidinium hexafluorophosphate (0.7 g, 2.51 mmol) in 15 mL of DCE, was heated to 60C for 72 hours. The crude was purified by flash column eluting with CH2CL2 : MeOH: NH40H (94.5 : 5: 0.5) to afford 0.25 g (50%) of the above titled compound as a dark FOAM. LU NMR (CD30D 3.31) 5 2.74 (s, 6 H), 3.79 (s, 4 H), 7.75 (d, 1 H, J = 1.17), 7.77 (s, 1 H), 8.01 (dt, 1H, J= 6.03, 0.96), 8.15 (m, 1 H), 8.59 (d, 1H, J= 6.03), 9.35 (d, 1H, J= 0.99) ; MS (ES+) M/Z 241.2 (M + H).
