Reaction Steps

Silica gel (Wakogel C-200, 0.03 g) was added as catalyst to a solution of 2-(3-chlorobenzoyloxy)-5-methyl-6-(4-pyridinyl)-2H-1,4-thiazin-3(4H)-one (0.79 g) and furan (0.30 g) in acetonitrile (30 ml) and the mixture was stirred at 50° C. for 35 hours. The mixture was chromatographed on silica gel (Wakogel C-200) column, using acetonitrile as an eluant. The residue was recrystallized from acetonitrile to give the titled compound (0.23 g, yield 37.7%) as pale orange crystals.
