4-Chloro-2-fluorobenzenemethanol Use and Manufacturing

1-(5-(4-Chloro-2-fluorobenzyloxy)pyridin-2-yl)-2-(2, 4-difluorophenyl)-1, 1-difluoro-3-(1H-tetrazol-1-yl)propan-2-ol (1)1-(Bromomethyl)-4-chloro-2-fluorobenzene was prepared using the following two-step procedure. To a stirred solution of 4-chloro-2-fluorobenzaldehyde (1.0 g, 6.31 mmol) in methyl alcohol (CHTo a solution of 4-chloro-2-fluorobenzoic acid (300mg) in THF (15m1) was added at 0°CLiAIH4 (130mg). The suspension was stirred at 0°C for 16h. The reaction mixture wasdiluted with EA and aq. solution of potassium sodium tartrate and stirred for lh at rt. The layers were separated and the org. phase was further washed with water. The combined org. layers were dried over MgSO4, filtrated off and evaporated in vacuo. The crude was purified by CC (Büchi Sepacore, 5g cartridge, solvent A: DCM, solvent B: 3N ammonia in MeOH, gradient in percentB: 0 to 5, flow rate: 6.0 mI/mm) to afford 224mg of colourless oil.
