Water → 6-chloro-2-ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-4-methyl-pyridine-3-carboxylic acid amide

Participants

Reaction Steps

A solution of 4.0 g (12.8 mmol) 2,6-dichloro-N-(3,5-difluorobenzyl)-4-methyl-pyridine-3-carboxylic acid amide in DMF (30 ml) was treated with 2.6 g (19.2 mmol) K2CO3 and 1.2 ml (16.0 mmol) ethanethiol, followed by stirring in a closed vessel at RT for 16 h. Then water (35 ml) was added and the mixture was extracted with EtOAc (2×70 ml). The combined organic layers were washed with water, a 2M aq. NaOH sol. and brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 3:1) provided 3.3 g (9.7 mmol, 76%) 6-chloro-2-ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-4-methyl-pyridine-3-carboxylic acid amide.
