Participants

Reaction Steps

A mixture of 2.2 g (0.010 mol) of chloromethyl(4-chlorophenyl)dimethylsilane and 1.1 g (0.012 mol) of 1,2,4-triazole sodium salt in 5 ml of dimethylformamide was warmed to 80°-90° for 2 hours, diluted with water, and extracted with ether. The ether solution was washed with water and brine, dried over magnesium sulfate, and evaporated to leave 2:1 g (83%) of the title compound as a yellow liquid: nD21 1.5428; ir (neat) 1555, 1470, 1245, 1130, 1080, 1010, 835, 805, 795, 735 cm-1 ; nmr (CDCl3) 0.4 (6H, s), 3.8 (2H, s), 7.4 (4H, broad s), 7.8 (1H, s), 7.9 (1H, s).
