In tetrahydrofuran; methanol; | (ii) 3,4,5-Trichlorobenzylalcohol To a stirred solution of <strong>[51-39-8]3,4,5-trichlorobenzoic acid</strong> (11.7g) in a mixture of dry THF (50ml) and trimethylborate (25ml) under N2 at room temperature was added boranedimethylsulphide complex (ca. 10M; 7.5ml) dropwise over 45 min. After stirring for a further 4 hours methanol (25ml) was added dropwise over 45 minutes. The mixture was stirred for a further 30 minutes then evaporated in vacuo . The residue was dissolved in ether, washed with 2M sodium hydroxide and brine, dried (MgSO4) and concentrated in vacuo . Trituration of the residue with hexane gave the title compound, 9.9g, mp. 106-108C. |

With acetic acid; sodium nitrite;copper(I) chloride; In hydrogenchloride; | (i) 3,4,5-Trichlorobenzoic acid To a stirred solution of 4-amino-3,5-dichlorobenzoic acid (Lancaster synthesis; 28g) in a mixture of concentrated sulphuric acid (200ml) and acetic acid (140ml) was added sodium nitrite (11.28g) in portions over 30 minutes. The mixture was stirred at room temperature for 5 hours then added slowly to a vigorously stirred suspension of freshly prepared cuprous chloride (20g) in concentrated hydrochloric acid (360ml). After standing overnight the precipitate was filtered, washed with water and dried in vacuo at 100C to provide the title compound. 28.6g, mp. 197-199C. |

Synthesis of 3,4,5-trichlorobenzoic acid (used in the synthesis of Compound 16) 3,4,5-Trichlorobenzoic acid was prepared from 4-amino-3,5-dichlorobenzoic acid, copper (II) chloride and tert-butyl nitrite in acetonitrile using the methodology used in the synthesis of 4-bromo-2,3,5,6-tetrafluorobenzoic acid. Nuclear magnetic resonance spectrum (NMR) was as follows: 'H (ppm from TMS in (CD3)2CO, integral, number of peaks): 8.05,2H,s. Mass spectrum M+ 224. |
