Procedure

To a solution of 2.5 equivalents 4-pyridin-3-yl-benzaldehyde in a mixture of methanol and glacial acetic acid is added 2-[3-(2-aminoethyl)-2-(3,5-dimethylphenyl)-1H-indol-5-yl]-1-(7-azabicyclo[2.2.1]hept-7-yl)-2-methyl-propan-1-one followed by 3 Å powdered molecular seives. To this mixture, an excess of sodium cyanoborohydride is added and the pH adjusted to 5.5 by the addition of 10% methanolic acetic acid. After completion, the reaction is quenched by the addition of saturated sodium bicarbonate and the mixture extracted with ethyl acetate. The organic portion is washed successively with saturated ammonium chloride, sodium bicarbonate and brine, then dried over sodium sulfate. Purification of the concentrate by flash chromatography on silica gel gives the title compound. MASS: 764 (M+H)
