HCID 15550491(2S)-2-(quinoline-8-sulfonylamino)-3-(4-(2-(1,4,5,6-tetrahydropyrimidin-2-ylcarbamoyl)-ethyl)-benzoylamino)-propionic acid tert-butyl ester

Reagents, catalysts & solvents 1

HCID 6228DimethylformamideSolvent

Procedure

65 mg (0.12 mmol) of (2S)-3-(4-(2-methoxycarbonyl-ethyl)-benzoylamino)-2-(quinoline-8-sulfonylamino)-propionic acid tert-butyl ester was dissolved in 1 ml of dimethylformamide and 59 mg (0.6 mmol) of 2-amino-1,4,5,6-tetrahydropyrimidine was added. The reaction was stirred at room temperature for 20 hours. The solvent was removed in vacuo and the residue was chromatographed on silica gel eluting with dichloromethane/methanol (1/1), followed by dichloromethane/methanol/acetic acid/water (85/15/1.5/1.5). Yield 72 mg. MS (ES+): m/e=609.3 (M+H+).
