実験手順

330 mg (3.75 mmol) of morpholine and 40 mg (0.56 mmol) of sodium cyanoborohydride are successively added to a solution of 80 mg (0.19 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-6-(4-formylphenyl)-1-benzothiophene-2-carboxamide hydrochloride (Example 23A) in 1.5 ml of a 6:1 mixture of methanol and acetic acid. 2 h at room temperature and 6 h at 80° C. are followed by purification by preparative HPLC. The product fractions are concentrated and, after addition of a 5:1 mixture of methanol and 1N hydrochloric acid, again concentrated. Drying under high vacuum results in 87.7 mg (88% of theory) of the title compound.
