Reaction Steps
Sodium amide was formed from sodium (1.0 g, 43.5 mmol) in liquid ammonia (100 ml) according to Example 1. Collidine (1) (5.0 g, 41.3 mmol) dissolved in tetrahydrofuran (5 ml) was added dropwise and after 45 min a well-cooled solution of dibromohexane (51.2 g, 210 mmol) in THF (100 ml) was added quickly. The reaction mixture was stirred for 1 h at -40° C. and then left stirring overnight during which times ammonia evaporated.
