A solution of ethyl 4,6-dichloronicotinate (1.14 g, 5.18 mmol), 2-thiophenemethylamine (0.530 mL, 5.17 mmol) and DIEA (1.80 mL, 10.3 mmol) in NMP (10 mL) was stirred at 90 C for 18 h. Water and EtOAc were added. The organic phase was washed with water, then was dried over Na2SO4, concentrated in vacuo to give ethyl 6-chloro-4-(thiophen-2-ylmethylamino)nicotinate as an oil (1.54 g).
