実験手順

Compound 31A is prepared according to the procedure described for compound 26A, using the following reactants: 2,4,6-trimethylaniline (4.8 ml, 34 mmol); bis(2-chloroethyl)amine hydrochloride (6.05 g, 34 mmol); sodium carbonate (1.8 g, 17 mmol); 1-butanol (75 ml). After impregnating onto silica, the crude reaction product is purified by flash chromatography with a mixture (95/5/1) and then (90/9/1) of dichloromethane/methanol/aqueous ammonia.
