Reaction Steps

A solution of 366 mg of N,N-diisopropylethylamine in 10 mL of methylene chloride was combined with 60 mg of 4-dimethylaminopyridine and 0.156 mL of 4-chlorobenzoyl chloride. This was treated dropwise with a solution of 500 mg of (1R,2S)-N-[N,N′-bis(tert-butoxycarbonyl)]amidino-2-(2-amino-6-methoxyquinazolin-4-yl)aminocyclohexylamine in 10 mL of methylene chloride, and stirred at room temperature for 3 hours. The reaction solution was combined with water, extracted with methylene chloride, and dried. After the solvent was distilled off, the residue was purified by column chromatography on silica gel (chloroform:methanol=30:1) to obtain 560 mg of the desirable compound.
