Versuchsvorschrift

Through the procedure as employed in Production step 1, an amine moiety derived from N-methylethanolamine (2.25 g) was introduced into 5-bromothiophene-2-carboxaldehyde (1.91 g), to thereby yield 5-[(2-hydroxy-ethyl)-methyl-amino]-thiophene-2-carbaldehyde (yield: 991 mg, 53%). The produced 5-[(2-hydroxy-ethyl)-methyl-amino]-thiophene-2-carbaldehyde (682 mg) was condensed with 3,4-dimethoxybenzyl cyanide (654 mg) through Method A (production step 2), to thereby yield the target product (yield: 300 mg, 24%).
