실험 절차

Through the procedure as employed in Production step 1, an amine moiety derived from morpholine (523 mg) was introduced into 5-bromothiophene-2-carboxaldehyde (382 mg), to thereby yield 5-morpholin-4-yl-thiophene-2-carbaldehyde (yield: 176 mg, 45%). The produced 5-morpholin-4-yl-thiophene-2-carbaldehyde (172 mg) was condensed with 3,4-dimethoxybenzyl cyanide (154 mg) through Method A (production step 2), to thereby yield the target product (yield: 46 mg, 15%).
