摘要 2-氯吡啶经氧化、亲核取代、Pd/C催化氢化得3-(吡啶-2-基氨基)丙酸乙酯(2)。另用对氯甲苯经氧化、硝化、胺化、酰氯化制得4-甲胺基-3-硝基苯甲酰氯(3)。2和3缩合得3-[(4-甲胺基-3-硝基苯甲酰基)(吡啶-2-基)氨基]丙酸乙酯(4),再经催化氢化还原、酰胺化后闭环、成脒及酰化反应等制得抗凝血药达比加群酯,总收率约12%(以对氯甲苯计)。 3-(Pyridin-2-ylamino)propinoic acid ethyl ester(2) was prepared from 2-chloropyridine by oxidation, substitution and then hydrogenation. 4-Methylamino-3-nitrobenzoyl chloride (3) was prepared from 4-chlorotoluene by oxidation, nitration, amination and chlorination. Dabigatran etexilate was synthesized from 2 and 3 by condensation, reduction, amidation, cyclization, amidination and acylation with an overall yield of about 12 % (based on 4-chlorotoluene).
