Procedure

A solution of 6-[(4-fluoro-3-methylphenoxy)methyl]-3-methyl-1,4-oxazepane (4-7, 13 mg, 0.051 mmol, 1 equiv), 5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid (16 mg, 0.077 mmol, 1.5 equiv), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC, 15 mg, 0.077 mmol, 1.5 equiv), 1-hydroxybenzotriazole (12 g, 0.077 mmol, 1.50 equiv) and triethylamine (21 uL, 0.15 mmol, 3.0 equiv) in DMF (5 mL) was stirred at 23° C. for 20 h. The reaction mixture was partitioned between saturated aqueous sodium bicarbonate solution and ethyl acetate (50 mL). The organic layer was dried over sodium sulfate and concentrated, and the residue was purified by flash column chromatography (100% hexanes initially, grading to 40% hexanes in EtOAc) to provide 6-[(4-fluoro-3-methylphenoxy)methyl]-3-methyl-4-[5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoyl]-1,4-oxazepane (4-8) as a mixture of diastereomers. LRMS m/z (M+H) 439.0 found, 439.2 required.
