Reaction Steps

To a suspension of 7-bromo-1,2,3,4-tetrahydro-isoquinoline hydrochloride (500 mgs, 2.0 mmol), pyridine-2-carboxylic acid (322 mgs, 2.61 mmol), HATU (992 mgs, 2.61 mmol), in DMF (2.5 mL) was added NMM (0.7 mL, 6.0 mmol) and the resulting solution was stirred at 23° C. for 3 h. The reaction mixture was then diluted with water/acetonitrile (15:1) and the resulting oil was then taken into EtOAc and washed with 1N HCl, NaHCO3, brine and dried (MgSO4). The mixture was the filtered and concentrated) to provide (7-bromo-3,4-dihydroisoquinolin-2(1H)-yl)(pyridin-2-yl)methanone.
