Procedure:
N-hydroxy-acetamidine (62 mg, 0.84 mmol) is added to a suspension of 3 Å molecular sieves in anhydrous THF (2 mL). After 20 min, NaH (60% in oil, 37 mg, 0.92 mmol) is added. The resulting suspension is stirred for 40 min and a solution of 3-(3,3-Dimethyl-2-oxo-1,2,3,4-tetrahydro-quinolin-4-yl)-3H-imidazole-4-carboxylic acid methyl ester (100 mg, 0.34 mmol) in THF (dry, 1 mL) is added. The resulting mixture is refluxed for 1 h. The solvent is removed under vacuum and the residue is purified by silca gel chromatography (mobile phase 0 to 40% ethyl acetate-heptane v/v), and gives the title compound (74 mg).

Procedure:
A mixture of 2-(benzo[b]thiophen-3-yl)-2-(benzylamino)acetic acid (I37) (303 mg, 1.02 mmol), (R)-quinuclidin-3-ol (156 mg, 1.22 mmol), DCC (252 mg, 1.22 mmol), and HOBT (187 mg, 1.22 mmol) in dry THF (20 ml) was stirred at room temperature overnight. The solvent was evaporated, and the crude product was partitioned between EtOAc and 2M K2CO3. The organic phase was washed with 2M K2CO3 and brine, dried over Na2SO4, filtered and evaporated to dryness. The crude product was purified by flash chromatography (CH3CN/MeOH=8/2+0.2% NH4OH) to obtain (R)-quinuclidin-3-yl 2-(benzo[b]thiophen-3-yl)-2-(benzylamino)acetate (53 mg, 12.8% yield).
