Reaction Steps

Through the procedure as employed in Production step 1, an amine moiety derived from N,N,N′-trimethylethylenediamine (6.13 g) was introduced into 5-bromothiophene-2-carboxaldehyde (3.82 g), to thereby yield 5-[(2-dimethylamino-ethyl)-methyl-amino]-thiophene-2-carbaldehyde (yield: 3.26 g, 77%). The produced 5-[(2-dimethylamino-ethyl)-methyl-amino]-thiophene-2-carbaldehyde (2.12 g) was condensed with 3,4-dimethoxybenzyl cyanide (1.77 g) through Method A (production step 2), to thereby yield the target product (yield: 1.20 g, 32%).
