N,N-Dimethylethylenediamine → HCID 68773949, compound

Participants

Reaction Steps

A stirred solution of 2-chloro-5-iodopyridine (0.50 g, 2.18 mmol) and N,N-dimethylethylenediamine (0.81 g, 1.00 mL, 9.20 mmol) in 2-ethoxyethanol (5 mL) was heated in a sealed tube under microwave irradiation at 125° C. for 1 h. The reaction mixture was then diluted with EtOAc (50 mL), washed with water (3×20 mL), dried (MgSO4), filtered and concentrated in vacuo. The residual oil was purified by column chromatography (SiO2, 3:1 EtOAc/MeOH) to give the title compound (0.22 g, 36%) as a viscous oil which solidified on standing. δH (CDCl3) 8.19 (1H, br. s), 7.53 (1H, m), 6.23 (1H, m), 3.29 (2H, m), 2.52 (2H, m), 2.24 (6H, s). Exchangeable proton not observed. LCMS (ES+) 292.0 (M+H)+.
