Procedure

A solution of 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (326 mg, 1.58 mmol), 5-bromonicotinic acid (300 mg, 1.5 mmol), HATU (627 mg, 1.65 mmol) and TEA (181.8 mg, 1.8 mmol) in DCM (15 mL) was stirred at 22° C. for 2 h, at which time the reaction mixture was diluted with water and extracted with DCM. The combined organic layers were dried and concentrated and the residue was purified by column chromatography to give title compound that was used in the next step without further purification (200 mg, Yield 34%). LCMS (m/z): 390/392 (M+1/M+2).
