Versuchsvorschrift
To a DMF solution of 3-(3-chlorobenzoyl)-2-ethylamino-6-methylpyridine were added chloroacetyl chloride and pyridine, followed by reaction at room temperature. Thereafter, the whole was worked up and purified in a usual manner to obtain N-[3-(3-chlorobenzoyl)-6-methylpyridin-2-yl]—N-ethylchloroacetamide. To an acetonitrile solution of the compound were added N-tert-butoxycarbonylpiperazine and potassium carbonate, followed by reaction under heating. Thereafter, the reaction mixture was worked up and purified in a usual manner to obtain 2-[4-tert-butoxycarbonylpiperazin-1-yl]—N-[3-(3-chlorobenzoyl)-6-methylpyridin-2-yl]-N-ethylacetamide. The resulting compound was reacted with sodium methoxide in methanol under heating. Thereafter, the reaction mixture was worked up and purified in a usual manner to obtain 3-(1 -tert-butoxycarbonylpiperazin-4-yl)-4-(3-chlorophenyl)-1-ethyl-7-methyl-1,8-naphthyridin-2(1H)-one. NMR1: 4.73 (2H, q, J=7.3 Hz), 3.15-3.35 (2H, m), 1.38 (9H, s).
