Methanaminium, N-((1H-benzotriazol-1-yloxy)(dimethylamino)methylene)-N-methyl-, hexafluorophosphate(1-) (1:1) → HCID 178432340, compound

Participants

Reaction Steps

To a suspension of lithium (S)-4-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(isoquinolin-3-ylcarbamoyloxy)pentanoate (0.43 mmol) and HBTU (244 mg, 0.64 mmol) in DMF (5 mL) was added 2-methyl-4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine dihydrochloride. The resulting mixture was stirred at RT for 1 h, filtered, and purified on RP-HPLC using a mixture of acetonitrile and water to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(2-methyl-6,7-dihydro-1H-imidazo[4,5-c]pyridin-5(4H)-yl)-5-oxopentyl isoquinolin-3-ylcarbamate (182.1 mg, 68% for two steps). LRMS (M+H+) m/z 622.2.
