95.2% In dichloromethane; N,N-dimethyl-formamide; EXAMPLE 45 Preparation of 2,4-Difluoro-5-nitrobenzoyl Chloride STR186 Oxalyl chloride (94.0 g, 0.739 mol) is added dropwise to a mixture of <strong>[153775-33-8]2,4-difluoro-5-nitrobenzoic acid</strong> (100.0 g, 0.492 mol), methylene chloride and N,N-dimethylformamide (0.600 ml). The resultant mixture is stirred 3.25 hours at reflux, cooled to room temperature, and concentrated in vacuo to afford the title compound as a brown oil (111 g, 95.2%).
