The crude product of the title compound was synthesized by conducting the similar reaction to that mentioned in Example 1 (1d) using 5-({[t-butyl(dimethyl)silyl]oxy}methyl)thiophene-2-carbonitrile (1.3 g, 5.0 mmol) that was obtained in Example 4 (4a) and a 40% aqueous solution of hydroxylamine (0.7 ml). Subsequently, the crude product of the title compound thus obtained was purified by recrystallization from a mixed solvent of ethyl acetate and hexane to afford the title compound (1.2 g) in a yield of 81% as a white crystalline solid.
