YieldReaction ConditionsOperation in experiment
With hydrogen bromide; copper(I) bromide; sodium nitrite 6.b EXAMPLE 6 b. An intimate dry mixture of 5-amino-2-methoxymethyl-(1,3,4)-thiadiazole (34.8 g) and sodium nitrite (75.9 g) was added over 1.5 hours to a stirred mixture of hydrobromic acid (48%, 270 ml) and cuprous bromide (2 g) maintained at -7°. The mixture was stirred at -6° for 1 hour and at room temperature for 1.5 hours. The mixture was neutralised with 10M NaOH, treated with sodium metabisulphite, warmed to 60° for 20 min., reneutralised with sodium hydroxide and filtered. The filtrate was extracted with cyclohexane for 13 hours, and the cyclohexane extract was dried over calcium sulphate, filtered and evaporated to give 5-bromo-2-methoxymethyl(1,3,4)thiadiazole (30.35 g) as an oil. (Found: C, 23.0; H, 2.7; Br 38.0; N, 13.5; S, 15.1; C4 H5 BrN2 OS requires C, 23.0; H, 2.4; Br 38.2; N, 13.4; S, 15.3 %).
