Deskripsi Produk
2. Dicampur 34,4 g produk langkah pertama dengan 240 mL diklorometana pada suhu kamar, dan aduk selama 1 jam dan dinginkan hingga -20 ° C. Tambahkan thionyl klorida 12 mL dan kemudian tambahkan N, N-dimethylformamide sekitar 0,5 mL, reaksi dilanjutkan selama 4 jam, sampai secara alami naik ke suhu kamar, kemudian menambahkan 29,12 g etil 3- (pyridin-2-ylamino) propionat dan 41,7 mL trietilamin, reaksi dilanjutkan selama 6 jam pada suhu kamar, Reaksi dipadamkan dengan 300 mL air dan lapisan organik dipisahkan. Fase organik dicuci dengan 200 mL natrium klorida berair jenuh, dikeringkan dengan natrium sulfat anhidrat dan dipekatkan di bawah tekanan yang dikurangi sampai volume total sekitar 100 mL. 50 mL n-heksana ditambahkan untuk mengendapkan padatan. Campuran diaduk pada suhu kamar selama 2,5 jam, Suction filtration, vakum kering selama 1 jam pada 50 ° C untuk memberikan senyawa target dabigatran etexilate intermediate CAS number 429659-01-8, ETHYL N- [4- (METHYLAMINO) -3 -NITROBENZOYL] -N-PYRIDIN-2-YL-SS-ALANINATE.
