YieldReaction ConditionsOperation in experiment
40% With tert.-butylnitrite; copper(ll) bromide; In acetonitrile; at -20 - 15℃; for 2h; To a solution of CuBr2 (4.03 g, 18.1 mmol) and t-butyl nitrite (2.82 mL, 23.8 mmol) in MeCN (210 mL) was added the compound of Example 170 (2.95 g, 15.9 mmol) at -20 C. The reaction mixture was slowly warmed to 15 C., at which point the evolution of N2 was observed. After stirring for an additional 2 hours at 15 C., the reaction mixture was diluted with Et2O (400 mL) and washed with a 10% solution of HCl (200 mL). The solvent layers were separated, the aqueous re-extracted with Et2O (2*300 mL), and the combined organic layers dried (MgSO4), filtered, and concentrated under reduced pressure. The residue was then purified by silica gel flash chromatography (98:2, hexanes/EtOAc) to afford bromide Example 172 (1.6 g, 40%) as a colorless oil that solidifies upon standing. (C7H8BrNO2S): LC-MS, RT 2.56 min., M+H 250.3; 1H NMR (CDCl3): delta 2.26 (s, 3H), 3.60 (s, 2H), 3.61 (s, 3H).
