This paper reports a novel synthesis of bosutinib starting from 3-methoxy-4-hydroxybenzoic acid. The process starts with esterification of the starting material, followed by alkylation, nitration, reduction, cyclization, chlorination and two successive amination reactions. The intermediates and target molecule were characterized by (1)H-NMR, (13)C-NMR, MS and the purities of all the compounds w...
The title compound, C(16)H(13)FO(2), was prepared from 4-methoxy-hypnone and 2-fluoro-benzophenone by a Claisen-Schmidt condensation reaction. The dihedral angle between the two benzene rings is 31.99 (2)°. In the crystal structure, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds along [010].
The title compound, C(15)H(13)N(3)O(4), was synthesized by the reaction of equimolar quanti-ties of 2-methoxy-benzaldehyde and 2-nitro-benzohydrazide in methanol. The dihedral angle between the two substituted benzene rings is 68.3 (2)°. In the crystal structure, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur.
BACKGROUND Helichrysum species are used extensively for stress-related ailments and as dressings for wounds normally encountered in circumcision rites, bruises, cuts and sores. It has been reported that Helichysum species are used to relief abdominal pain, heart burn, cough, cold, wounds, female sterility, menstrual pain. RESULTS From the extracts of Helichrysum foetidum (L.) Moench, six know...
The structure of the title compound (4BPBA), C(13)H(9)BrO(2), is similar to that of phenyl benzoate (PBA), 4-methyl-phenyl benzoate (4MePBA) and 4-methoxy-phenyl benzoate, with somewhat different bond parameters. The dihedral angle between the phenyl and benzoyl rings in 4BPBA is 58.43 (17)°, compared with values of 55.7° in PBA and 60.17 (7)° in 4MPBA. The mol-ecules in the title compound are ...
