Tributyltin azide → 2-(2,4-dichlorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-(2-tribut-1-ylstannyltetrazol-5-yl)propan-2-ol

Participants

Reaction Steps

A paste of tri-n-butyltin azide (2.45 g) and 1-cyano-2-(2,4-dichlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propan-2-ol (2.0 g) was heated at 160° C. for three hours. A further quantity of tri-n-butyltin azide (0.2 g) was added and the heating continued for a further hour to complete the reaction. The resulting viscous oil was triturated with ethyl acetate and the product collected and dried under vacuum to give 2-(2,4-dichlorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-(2-tribut-1-ylstannyltetrazol-5-yl)propan-2-ol as a crystalline solid (3.1 g, 73%) m/e 628.
