Electric Literature of 327056-73-5, The chemical industry reduces the impact on the environment during synthesis 327056-73-5, name is 3-Chloro-5-fluorobenzonitrile, I believe this compound will play a more active role in future production and life.
EXAMPLE 2 ^_(4-{(lJR)-14(R)-(3-CHLORO-5-CYANOPHENOXY)(4- CHLOROPHENYL)METHYL]BUTYL}BENZOYL)~beta-ALANINETo a solution of INTERMEDIATE 1 (100 mg, 0.239 mmol) and 3-chloro-5- fluorobenzonitrile (40.9 mg, 0.263 mmol) in DMF (2 mL) was added potassium tert-butoxide (107 nig, 0.957 mmol), then the resulting mixture was allowed to stir at 120 0C for 16 hours. After being allowed to cool to RT, the mixture was diluted with 2 N HCl (aq) then extracted with EtOAc. The organic layer was washed twice with water then concentrated. The resulting yellow residue was purified by preparative reverse phase HPLC eluting with 30-100% CHaCN/water + 0.1% TFA. Following lyophilization, this afforded the title compound as a white solid. 1H NMR (500 MHz, CD3OD): 6 7.70 (d, J – 8.5 Hz, 2 H); 7.34 (d, J = 8.5 Hz, 2 H); 7.30 (d, J = 8.0 Hz, 2 H); 7.25 (d, J – 8.5 Hz, 2 H); 7.20 (s, 1 H); 7.09 (s, 1 H); 7.06 (s, 1 H); 5.55 (d, J = 6.5 Hz, 1 H); 3.61 (t, J = 7.0 Hz, 2 H); 3.16 (m, 1 H); 2.62 (t, J = 7.0 Hz, 2 H); 1.80 (m, 1 H); 1.54 (m, 1 H); 1.11-1.07 (m, 2 H); 0.78 (t, J = 7.2 Hz, 3 H); LC3 3.93 min. (M+H)+ 523.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Chloro-5-fluorobenzonitrile, other downstream synthetic routes, hurry up and to see.
