63% In toluene; at 100℃; for 1h; To a solution of bromide from Step 1 (18 g, 86 [MMOL)] in toluene (100 mL) was added thiourea (10.5 g, 138 [MMOL).] The reaction mixture was heated to [100C] for 1 h, cooled to rt, and the solvent removed under reduced pressure. The residue was dissolved in [CH2CI2] (100 mL), a saturated solution of [NAHC03] (75 mL) was added, and the mixture was vigorously stirred for 10 minutes. The organic layer was separated, dried [(NA2SO4),] filtered, and concentrated under reduced pressure.

YieldReaction ConditionsOperation in experiment
60% To a solution of the compound prepared in Step 2 (5.00 g, 26.8 [MMOL)] and DMAP (32 mg, 0.26 [MMOL)] in [CH2C12] (150 mL) was added BOC2O (7.00 g, 32.2 [MMOL).] After 4 h, additional quantities of [BOC20] (7.00 g, 32.2 [MMOL)] and Et3N (7.50 mL, 53.6 [MMOL)] were added. The reaction mixture was stirred at rt for 18 h, then a saturated solution of [NH4CI] (100 mL) was added and the reaction was stirred for 15 minutes. The layers were separated, dried [(NA2SO4),] filtered, and concentrated under reduced pressure. The residue was passed through a short plug of silica gel to yield a mixture of the corresponding mono-and di-carbamate. This mixture was dissolved in [MEOH] (40 mL), and a [1 N SOLUTION] of [NAOH] (20 mL) was added. The solution was stirred for 90 minutes, the methanol removed under reduced pressure and the residue was washed with [ET20] (2 x 10 mL). The aqueous layer was acidified to [PH # 4 ] using 1 N HCI, extracted with CH2CI2 (2 x 50 mL), and the combined organic layers dried [(NA2SO4),] filtered and concentrated under reduced pressure to afford the desired product as a yellow solid (4. [4 G,] 60%). (C11H16N2O4S) : LC-MS, [RT 2.] 39 min, (M+H) [+ 272.] 9 ;'H NMR [(CDCI3)] : [6] 1.51 (s, 9H), 2.32 (s, 3H), [3.] 61 (s, 2H).

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.
