Reaction Steps

Combine 2-(6,8-Difluoro-1,2,3,4-tetrahydro-naphthalen-2-ylamino)-pentanoic acid (1 equiv) derived from diasteromer #1 above, TPTU (1 equiv), diisopropylethylamine (2 equiv) in DMF followed by 1-[2-(2,2-dimethyl-propylamino)-1,1-dimethyl-ethyl]-1H-imidazol-4-ylamine (2 equiv) in methylene chloride. The reaction is stirred overnight at rt, quenched with aq. sodium bicarbonate, and extracted with methylene chloride. The solvent is dried, concentrated, and purified by silica gel chromatography to afford diastereomer #1 of the title compound.
