Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 93919-56-3, name is (4-(Trifluoromethoxy)phenyl)methanamine, This compound has unique chemical properties. The synthetic route is as follows., Formula: C8H8F3NO
A mixture of (R) -7-hydroxy-5, 6,7, 8-tetrahydro-naphthalen-1-yl)-carbamic acid phenyl ester (147.3 mg, 0.52 mmol) and 4-trifluoromethoxy-benzylamine (99.4 mg, 0.52 mmol) in DMSO (1.5 ml) was stirred at 150 °C for 1.5 hours. The reaction mixture was cooled to room temperature, and ethylacetate and water were added. The extracted organic layer was washed with water then brine, dried over Na2S04, filtered and concentrated under reduced pressure. The obtained residue was triturated with dichloromethane and hexane to obtain N-{(R)-7-hydroxy-5, 6,7, 8-tetrahydro- naphthalen-l-yl}-N’-(4-trifluoromethoxy-benzyl)-urea (168.0 mg, 85 % yield). ‘H NMR (DMSO-d6) 5 1.54-1. 65 (m, 1H), 1. 81-1. 92 (m, 1H), 2.25-2. 38 (m, 1H), 2.68-2. 88 (m, 3H), 3. 86-3. 98 (m, 1H), 4.32 (d, J= 6.0 Hz, 2H), 4.85 (d, J= 4.1 Hz, 1H), 6. 72 (d, J=7. 5 Hz, 1H), 6.98 (t ; J= 7.5 Hz, 1H), 7.06 (t, J= 6.0 Hz, 1H), 7.34 (d, J=8.3 Hz, 2H), 7.43 (d, J=8.7 Hz, 2H), 7. 63 (d, J=7.5 Hz, 1H), 7.5 (s, 1H). Molecular weight : 380. 36 MS (M+H): 381 In vitro activity class: A Chiral HPLC (ChiralCel AD 0.49 cm x 25 cm column, n-hexane/ethanol = 90/10, flow rate 1.5 rnL/rnin) R-isomer was detected at 17.7 minutes.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 93919-56-3.
