Versuchsvorschrift

To a solution of 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 (15 mg in a mixture of 1.0 mL dry chloroform and 0.10 mL methanol) at 0° C. was added 25 mg magnesium sulfate followed by 5-pyridin-3-yl-thiophene-2-carbaldehyde (9.3 mg) and the mixture stirred at low temperature. After 40 minutes, 0.070 mL of acetic acid were added followed by a solution of sodium cyanoborohydride (4.4 mg in 0.10 mL methanol) and the mixture allowed to warm to room temperature. After 20 hours, the reaction was quenched by the addition of saturated aqueous sodium bicarbonate, extracted with methylene chloride and the combined organics washed sequentially with water and brine. Purification of the concentrate by preparative tlc on silica gel (ethyl acetate) followed by preparative reverse phase HPLC (water:acetonitrile, 60:40) gave the title compound (3.2 mg). MASS: 602 (M+H)
