YieldReaction ConditionsOperation in experiment
72% With tert.-butyl lithium; In tetrahydrofuran; pentane; Preparation 1 Compounds of Formula (B) 1,3-Dibromo-5-ethyl-benzene (1.54 g, 5.8 mmoles) was dissolved into anhydrous THF (20 mL) under nitrogen, and was chilled to -78 C. To this stirring solution was slowly (over 10 min) added t-BuLi (3.8 mL, 6.5 mmoles, 1.7M solution in pentane). After the addition was complete the mixture was allowed to stir at -78 C. for an additional 30 min. After this period isopropyl disulfide (1.4 mL, 8.8 mmoles) was added and the mixture was allowed to warm to ambient temperature. The reaction was then warmed to 75 C., and was stirred at this temperature for 16 hours. After this period the reaction mix was evaporated in vacuo and was purified using flash silica chromatography (0-1% EtOAc/Hexane) to yield 1-bromo-3-ethyl-5-isopropylsulfanyl-benzene (1.08 g, 72%) as a clear liquid. 1H-NMR (CDCl3): δ 7.34-7.32 (m, 1H), 7.19-7.17 (m, 1H), 7.13-7.11 (m, 1H), 3.39 (m, J=6.6 Hz, 1H), 2.59 (q, J=7.6 Hz, 2H), 1.30 (d, J=6.6 hz, 6H), 1.22 (t, J=7.6 Hz, 3H).

YieldReaction ConditionsOperation in experiment
40% With tert.-butylnitrite; In dichloromethane; Precursor alpha: 2,3-Dichloro-5-isopropylthiopyridine 13.1 g (0.08 mol) of <strong>[98121-41-6]3-amino-5,6-dichloropyridine</strong> in 120 ml of methylene chloride were reacted with 25 g (0.16 mol) of diisopropyl disulfide and 12.4 g (0.12 mol) of tert-butyl nitrite in 70 ml of methylene chloride by a method similar to Example 1, Precursor alpha. This gave 30 g of the dark oil (approximately 40% of product of value) which was further reacted without further purification. 1H-NMR (in d6 dimethyl sulfoxide): delta [ppm]=1.25 (d, 2*CH3); 3.7 (m, CH); 8.2 and 8.3 (2*d, pyr H).
