Reaction Steps

To a cooled (0° C.) suspension of 2-(2-(6-methoxynaphthalen-2-ylsulfonyl)-1,2,3,4-tetrahydropyrrolo[1,2-a]pyrazin-1-yl)acetic acid (S2) (310 mg, 0.77 mmol, 1.0 eq.) in DCM (20 ml) was added HATU (600 mg, 1.54 mmol, 2 eq.) and DIPEA (0.4 ml, 2.31 mmol, 3 eq.) and the reaction mixture was allowed to stir for 30 min. Finally, 6-((tert-Butylamino)methyl)-1,2,3,4-tetrahydronaphthalen-2-amine (A15) (180 mg, 0.77 mmol, 1.0 eq.) was added and the reaction mixture and it was stirred at RT for 16 h. The mixture was diluted with DCM (100 ml) and successively washed with ammonium chloride solution (50 ml), sodium bicarbonate solution (50 ml), water (10 ml) and brine (10 ml). The organics were dried over Na2SO4 and the solvent was evaporated under reduced pressure to give the crude product which was purified by column chromatography (silica gel, 6% MeOH/DCM) to yield the pure title compound as a white solid. Yield: 34% (160 mg, 0.26 mmol); MS, Rt=3.6 min; m/z=615.1 [MH]+
