Synthetic Route of 60781-83-1, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 60781-83-1, name is 4-Phenylpyridin-2-amine, molecular formula is C11H10N2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a solution of (R)-4-BOC-2-morpholinecarboxylic acid (CAS Number 884512-77-0; 0.250 g, 1 .08 mmol) in DMF (15 ml) was added HATU (0.617g, 1 .62 mmol) at rt. The reaction mixture was stirred at rt for 30 min. 4-Phenylpyridin-2- ylamine (CAS Number 60781 -83-1 ; 0.184 g, 1 .08 mmol) and TEA (0.46 ml, 3.246 mmol) were added and the reaction mixture was stirred at rt for 72 h. The resulting reaction mixture was poured into water (25 ml) and extracted with EtOAc (3 x 25 ml). The combined organic layer was dried over Na2S04, filtered and concentrated under reduced pressure. The resulting residue was purified by flash chromatography (4% MeOH in DCM) yielding tert-butyl (R)-2-((4-phenylpyridin-2-yl)carbamoyl)morpholine- 4-carboxylate (0.1 15 g, 0.300 mmol). LCMS: Method C, 2.423, MS: ES+ 384.38; 1 H NMR (400 MHz, DMSO-d6) delta ppm: 9.86 (s, 1 H), 8.41 (d, J=5.2 Hz, 1 H), 8.36 (s, 1 H), 7.74 (d, J=6.8 Hz, 2 H), 7.48 – 7.57 (m, 4 H), 4.17 – 4.20 (m, 1 H), 4.01 – 4.03 (m, 2 H), 3.71 – 3.74 (m, 1 H), 3.53 – 3.58 (m, 1 H), 2.89 – 3.01 (m, 2 H), 1 .42 (s, 9 H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 60781-83-1, 4-Phenylpyridin-2-amine.
