51% With tert.-butylnitrite; copper(ll) bromide; In acetonitrile; at 45℃; for 3h; A slightly yellow solution of 2,5-difluoro-4-(trifluoromethyl)aniline (10.0 ml; 76.708 mmol) in MeCN (90 ml) was treated with copper(ll) bromide (17.133 g; 76.708 mmol), and the green heterogeneous mixture was heated to 45C. A solution of tert-butyl nitrite (10.0 ml; 84.379 mmol) in MeCN (20 ml) was then added dropwise over 30 min., and the resulting mixture was further stirred at 45C for 2h30. The dark-green heterogeneous reaction mixture was allowed to cool to rt, and was directly purified by FC (DCM). After concentration to dryness under reduced pressure, the expected product 1-bromo-2,5-difluoro-4-trifluoromethyl- benzene was obtained as an orange oil (10.290 g; 51 %). LC-MS: tR = 1.07 min.; [M+H]+: no ionisation.

Step 3: Preparation of (S)-N-((R)-((1s,3S)-3-((tert-butyldimethylsilyl)oxy)cyclobutyl)(2,5-difluoro-4-(trifluoromethyl)phenyl)methyl)-2-methylpropane-2-sulfinamide To a 100 mL oven-dried 3 necked round bottom flask under nitrogen was added <strong>[261945-75-9]1-bromo-2,5-difluoro-4-(trifluoromethyl)benzene</strong> (1.09 g, 3.45 mmol) in anhydrous THF (15 mL). The resulting solution was cooled to -70 C (internal temperature) with an acetone dry-ice bath. Isopropylmagnesium chloride lithium chloride complex (2.79 mL, 3.62 mmol, 1.3 M) was then added dropwise while maintaining the internal reaction temperature between -65 C and -70 C. The resulting solution was stirred at -70 C for 30 minutes, and then (S)-N-((Z)-((1s,3R)-3-((tert-butyldimethylsilyl)oxy)cyclobutyl)methylene)-2-methylpropane-2-sulfinamide in 5 mL THF was added dropwise while maintaining the internal temperature between -65 and -70 C. The resulting solution was stirred at the same temperature for 120 minutes, and then the dry-ice was removed from the cooling bath and the reaction was allowed to warm to 0 C over 30 minutes and at rt overnight (no reaction observed at 0 C-reaction proceeded at rt). It was then quenched with 30 ml saturated ammonium chloride (aqueous) and then diluted with 40 mL ethyl acetate and 40 mL water. The layers were shaken and separated and the organic phase was washed with brine, dried over sodium sulfate and concentrated to a crude sticky solid which was purified with silica gel using a gradient from 0 to 20% ethyl acetate/hexanes, providing the desired product as a white foam (1.06 g, 1.91 mmol, 2:1 mixture of diastereomers).
