Procedure

To a solution of 8-methyl-1,2,3,4-tetrahydroquinoline (1) (2.77 g, 18.8 mmol) in dry CH2Cl2 (50 mL) at 0° C. was added chloroacetyl chloride (1.80 mL, 22.6 mmol) followed by dropwise addition of Et3N (6.30 mL, 45.2 mmol). The reaction was stirred overnight under N2. The reaction mixture was then diluted with CH2Cl2 (50 mL), washed with water (2×15 mL), and saturated NaCl (15 mL). Dried over MgSO4, filtered, and concentrated to give compound 2 (3.7 g). This crude material was used in subsequent reactions without further purification.
