Electric Literature of 1142363-52-7, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1142363-52-7, name is JNJ-40346527, molecular formula is C27H35N5O2, molecular weight is 461.5991, as common compound, the synthetic route is as follows.
Example 25 4-Cyano-1H-imidazole-2-carboxylic acid[2-(4,4-dimethyl-cyclohex-1-enyl)-6-(2,2,6,6-tetramethyl-tetrahydro-pyran-4-yl)-pyridin-3-yl]-amide(1S)-(+)-10-camphorsulfonic acid salt A solution of 4-cyano-1H-imidazole-2-carboxylic acid[2-(4,4-dimethyl-cyclohex-1-enyl)-6-(2,2,6,6-tetramethyl-tetrahydro-pyran-4-yl)-pyridin-3-yl]-amide (52.4 mg, 0.113 mmol, as prepared in Example 15, step (h)) in EtOH (2 mL) was treated with (1S)-(+)-10-camphorsulfonic acid (26.4 mg, 0.113 mmol) at room temperature for 1 h. The solvents were evaporated in vacuo, and the residue was dried under high vacuum overnight. The solid was dissolved in a minimum amount of EtOH (1 mL) with sonication and heating. While warm, the solution was slowly treated with hexanes until first precipitate was seen at the surface of the solution. The mixture was allowed to stir 30 min at room temperature while material continued to precipitate. The solid was filtered and air-dried to afford the title compound (66.2 mg, 84%) as white crystals. 1H-NMR (CD3OD; 400 MHz): delta 9.17 (d, 1H, J=8.4 Hz), 8.10 (s, 1H), 7.95 (d, 1H, J=8.4 Hz), 6.39-6.32 (m, 1H), 3.76-3.64 (m, 1H), 3.38-3.34 (m, 2H), 2.80-2.75 (m, 1H), 2.75-2.65 (m, 1H), 2.54-2.45 (m, 2H), 2.40-2.30 (m, 1H), 2.25-2.18 (m, 2H), 2.10-2.00 (m, 2H), 1.98-1.86 (m, 3H), 1.76-1.66 (m, 4H), 1.65-1.56 (m, 1H), 1.47-1.38 (m, 7H), 1.30 (s, 6H), 1.15 (m, 9H), 0.87 (s, 3H). Mass spectrum (APCI, m/z): Calcd. for C27H35N5O2, 462.3 (M+H), found 462.3.
The chemical industry reduces the impact on the environment during synthesis 1142363-52-7, I believe this compound will play a more active role in future production and life.
