N,N-Dimethylethylenediamine → 2-Benzyl-6-(5-(cyclopropylcarbamoyl)-2-methylphenyl)-N-(2-(dimethylamino)ethyl)-1-oxo-1,2-dihydroisoquinoline-4-carboxamide

Participants

Reaction Steps

To a mixture of the product of step iii) (0.48 g) and N,N-dimethylethane-1,2-diamine (0.17 mL) in THF (20 mL) was added N,N-diisopropylethylamine (0.56 mL) followed by HATU (0.60 g) and the reaction stirred at room temperature for 3 hours. The reaction mixture was concentrated to dryness and the crude product purified by SiO2 chromatography (eluting with 90:10:0.1 dichloromethane:methanol:triethylamine). The fractions containing product were concentrated to dryness and the residue triturated with acetonitrile to give the title compound as a solid (0.35 g).
