Procedure
Operations similar to Production Example 1-(1) were conducted using 1-tetrahydro-3-furanyl-1-propanone in place of 3-methyl-2-butanone, and successively those of Production Example 1-(2) were conducted using 2-amino-5-nitropyridine. The resulting solid was suspended in ethyl acetate, washed with saturated aqueous sodium hydrogencarbonate solution and purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to provide the title compound as yellow crystals.
Workup
- washwashed with saturated aqueous sodium hydrogencarbonate solution
- custompurified by silica gel column chromatography (hexane/ethyl acetate=2/1)
