Dimethylamine → Methyl 6-chloro-4-(dimethylamino)nicotinate

関与物質

反応手順

Dimethylamine (1.23 mL, 9.71 mmol) was slowly added to a stirred solution of methyl 4,6-dichloronicotinate (0.40 g, 1.94 mmol) in MeCN (6 mL) at room temperature. The solution was stirred at room temperature for 18 hours then concentrated in vacuo onto silica gel. Gradient chromatography, eluting with 5% EtOAc:c-Hex over 5 column volume and 5-50% over 15 column volume, gave methyl 6-chloro-4-(dimethylamino)nicotinate (335 mg, 1.56 mmol, 80% yield) as a white solid.
