To a solution of 1-(piperazin-1-yl)isoquinoline (459 mg, 2.15 mmol) in THF (15 mL) was added NEt3 (3.6 mL, 27 mmol) and chloroacetonitrile (1.8 mL, 28 mmol) and the reaction was stirred 3 h. The reaction mixture was filtered, concentrated and the residue purified by silica gel chromatography (Biotage 25-short, 25% EtOAc/hexanes to 100% EtOAc/hex) to yield 38 (188 mg, 0.75 mmol, 35%) as a white solid. LC/MS: (ES+) m/z (M+H)+=253; HPLC Rt=1.23 min., column Q, conditions B.
