Through the procedure as employed in Production step 1, an amine moiety derived from 4-hydroxypiperidine (3.03 g) was introduced into 5-bromothiophene-2-carboxaldehyde (1.91 g), to thereby yield 5-(4-hydroxypiperidin-1-yl)-thiophene-2-carbaldehyde (yield: 1.36 g, 64%). The produced 5-(4-hydroxypiperidin-1-yl)-thiophene-2-carbaldehyde (1.27 g) was condensed with 3,4-dimethoxybenzyl cyanide (1.06 g) through Method A (production step 2), to thereby yield the target product (yield: 1.09 g, 50%).
