2-Furanmethanethiol → 8-chloro-N-[4-[(2-furanylmethyl)thio]-2-oxobutyl]dibenz[b,f][1,4]oxazepin-10(11H)-carboxamide

Participants

Reaction Steps

A solution of 8-chloro-N-(2-oxo-3-butenyl)dibenz[b,f][1,4]oxazepin-10(11H)-carboxamide (0.75 gram), furfuryl mercaptan (0.23 mL), piperidine (0.069 mL), and N-benzyltrimethylammonium hydroxide (0.069 mL) in methylene chloride (12 mL) and methanol (3 mL) was stirred at room temperature for 6 hours. The reaction was diluted with methylene chloride (75 mL), washed with 75 mL each of 1N HCl (two times), water, saturated aqueous sodium bicarbonate, and brine, dried over MgSO4, and evaporated in vacuo. The crude product was purified by flash chromatography through silica gel 60 (350 mL) using 95:5 methylene chloride: ethyl acetate to yield a colorless oil. Analysis calculated for C23H21ClN2O4S×0.1 EtOAc: C, 60.34; H, 4.72; N, 6.01; Cl, 7.61; S, 6.88. Found: C, 59.94; H, 4.84; N, 5.87; Cl, 8.13; S, 6.65.
