Part A: To mixture of 345 mg (1.43 mmol) of 4-amino-N,N-dimethyl-N′-(methylsulfonyl)benzamidine, 1.5 mL of EtOH, and 0.5 mL of H2O heated at 100° C. was added portion-wise 311 mg (1.43 mmol) of 5-chloro-N-(oxiran-2-ylmethyl)thiophene-2-carboxamide. After 8 hours, the volatiles were evaporated and the compound purified by purified by ISCO System flash chromatography (Gradient elution 0% to 100% B over 40 min; (A=Hexane, B=AcOEt) then 0% to 100% B over 30 min; (A=AcOEt, B=5% MeOH and 1% NH4OH)) to yield 320 mg of N-(3-(4-(N,N-dimethyl -N′-(methylsulfonyl)carbamimidoyl)phenylamino)-2-hydroxypropyl)-5-chlorothiophene-2-carboxamide as a yellow oil. Further purification by prep HPLC yield an analytically pure sample.
