実験手順

A solution of 6-[4-(3,6-dihydro-4-phenyl-1(2H)-pyridinyl)-1-butynyl]-3-pyridinamine (Example 20) (1.5 g, 0.005 mol), triethylamine (0.76 mL, 0.0054 mol) and N,N-dimethylaminopyridine (catalytic amount) in 50 mL of dichloromethane is cooled to 0° C. and acetyl chloride (0.42 mL, 0.006 mol) is added dropwise. The cold bath is removed and the solution is stirred at room temperature for 1 hour. The reaction is quenched with saturated aqueous sodium bicarbonate, the organic layer is washed with water and dried (sodium sulfate), and the solvent is removed under reduced pressure. The residue is chromatographed (silica gel, 2% methanol/98% dichloromethane) to give the title compound, containing 0.35 mol of water; mp 158.5°-159.5° C.
