It is a common heterocyclic compound, the quinuclidine compound, Ethyl quinuclidine-4-carboxylate, cas is 22766-68-3 its synthesis route is as follows.
Step 1. A solution of 4-carbethoxyquinuclidine (10.92 g) in THF (155 mL) was treated at-780C with borane-THF (1.0 M, 77.5 mL). The resulting mixture was stirred at -78C for 4 h, then treated with water (50 mL), warmed to room temperature and stirred for an additional hour. The reaction mixture was diluted with ethyl acetate and the aqueous phase was separated and extracted with two further portions of ethyl acetate. The combined organic layers were washed with brine- (twice), dried (MgSO4), filtered and evaporated in vacuo. Purification by silica gel chromatography (eluting with cyclohexane-ethyl acetate [1 :0 to 1 :1]) gave 1-boranyl-1-aza-bicyclo[2.2.2]octane-4- carboxylic acid ethyl ester (7.12 g, 61%) as an off-white solid. 1H NMR (400 MHz, CDCI3) delta 4.16 (2H1 q, J = 6.9), 3.10-3.05 (6H1 m), 1.98-1.93 (6H, m), 1.26 (3H, t, J = 6.9).
