Potassium Carbonate → HCID 46908820, compound

Participants

Reaction Steps

227 mg (1.65 mmol) of K2CO3 were added to a solution of 375 mg (1.5 mmol) of 2-mercapto-N-(thiophen-2-ylmethyl)nicotinamide in DMF (3.5 ml), and stirring was carried out for 30 min at RT. 252 mg (1.5 mmol) of 3-chloro-1-phenylpropan-1-one were then added and stirring was carried out for a further 2 d at RT. The mixture was then concentrated in vacuo and the residue was taken up in a mixture of EA and a 1N aq. NaHCO3 sol. The organic phase was separated off and the aqueous phase was extracted again with EA. The combined organic phases were dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by means of CC (EA/hex 1:1), and subsequent crystallization (EA/hexane) yielded 73 mg (0.2 mmol, 13%) of 2-[(3-oxo-3-phenyl-propyl)sulfanyl]-N-(thiophen-2-yl-methyl)-pyridine-3-carboxylic acid amide. MS: m/z 383.1 [M+H]+.
