Argatroban (USAN:INN:BAN:JAN) → Methyl 6-aminohexanoate

Participants

Reaction Steps

To a solution of argatroban monohydrate (300 mg, 0.570 mmol) and methyl 12-aminododecanoate (compound YS-004-17) (132 mg, 0.576 mmol) in anhydrous DMF (15 mL) was added HBTU (258 mg, 0.680 mmol). Stirring was continued at room temperature for 16 hours. The precipitates formed during the reaction were filtered off and DMF was removed by vacuum distillation. The residue was purified by preparative TLC using solvents CH2Cl2 /MeOH/NH3 (90/10/1, v/v) to give the titled compound (140 mg) (Yield: 28%). 1HNMR (MeOH-4, 300 MHz).
