反応手順
Phenethylamine (285 mg) and N-(benzyloxycarbonyl)-D-alanine (500 mg) were condensed (618 mg, 85%) using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (472 mg) in dichloromethane. (R)-2-amino-N-phenethylpropanamide (197 mg) obtained by further hydrogenation reaction in the presence of 10% palladium-carbon, and isoquinoline-6-sulfonyl chloride prepared in Reference Example 1 were condensed (237 mg, 60%) in the presence of triethylamine (0.284 mL) in dichloromethane. Subsequently, 40 mg of the title compound was obtained as a pale yellow solid (13%) with reference to the method of Step 3 of Example 1.
