Intermediate 11 -l-(2-methylallyl)-lH-l,2,4-triazole To 3,5-dibromo-lH-l,2,4-triazole (1.5 g, 6.61 mmol) in DMF (13 mL) was added sodium tert- pentoxide (0.728 g, 6.61 mmol) and the mixture was stirred for 10 min at rt under nitrogen atmosphere. 3-Bromo-2-methylprop-l-ene (0.667 mL, 6.61 mmol) was added and the mixture was stirred at 40C for 2 hours. The mixture was poured onto water and extracted with diisopropylether (2x). The organic phase was washed with water (2x), brine and dried over sodium sulfate. The solvents were evaporated to give the title compound as a liquid (1.70 g, 91%). GCMS (CI) m/z 281 [M+]. XH NMR (400 MHz, CDCI3) delta ppm 1.74 (d, 3 H) 4.69 (s, 2 H) 4.81 – 4.86 (m, 1 H) 5.05 (dd, 1 H).
