With oxalyl dichloride In dichloromethane; N,N-dimethyl-formamide at 20℃; Reflux; | A.1 Step 1: Synthesis of 3-fluoro-N-(1-hydroxy-2-methylpropan-2-yl)-4-(trifluoromethyl)benz-amide 10.0 g (48.0 mmol) of 3-fluoro-4-(trifluoromethyl)benzoic acid were initially charged in 40 ml of CH2Cl2, and five drops of DMF were added. 7.93 g (62.4 mmol) of oxalyl chloride were added slowly at room temperature (RT), and the mixture was, after the evolution of gas had ceased, heated under reflux until the reaction had gone to completion. The mixture was concentrated and then distilled once more with toluene. In a temperature range of 5-25° C., a solution of this crude acid chloride in 40 ml of CH2Cl2 was added dropwise to a solution of 8.57 g (96.1 mmol) of 2-amino-2-methylpropanol in 20 ml of CH2Cl2. The mixture was then stirred in an ice bath for 1.5 h and subsequently thawed to RT over a period of 16 h. The precipitated hydrochloride was separated off, the residue was washed with a large quantity of CH2Cl2 and the filtrate was evaporated to dryness. This gave 8.40 g of product of a purity of about 80%. Furthermore, the residue separated off at the beginning of the work-up was triturated with water and filtered again. The residue obtained was another 4.60 g of clean product. | |

The mixture was concentrated under vacuum and azeotropically dried twice with 5 mL of toluene to obtain 55 mg of 3-fluoro-4-(trifluoromethyl)benzoyl chloride. |
