二异丙基氨腈

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 5,6,7,8-tetrahydroquinoline (6.5 ml, 50 mM) in benzene (35 ml) maintained below 10° was treated with 1.6M butyl lithium in hexane (31.25 ml, 50 mM). The resulting anion solution was heated to reflux then treated with a solution of diisopropylcyanamide (6.3 g, 50 mM) in benzene (15 ml). After 15 min. the mixture was cooled and quenched with water (20 ml). The organic phase was separated, dried and evaporated. Distillation of the residue gave the title compound (5.6 g, 71%) Bp. 135°-140°/2 mm, identical with authentic material. Hydrochloride mp 185° C.--see Example 37 UK Pat. No. 1,432,378. The resulting anion solution was heated to reflux After 15 min. the mixture was cooled quenched with water (20 ml) The organic phase was separated dried evaporated Distillation of the residue
