Reaction Steps

A solution of (±)-2-chloro-α-(4-chlorophenyl)-4-(4,5-dihydro-3,5-dioxo-1,2,4-triazin-2(3H)-yl)-α-methylbenzeneacetyl chloride (0.007 mol) in CH2Cl2 (20 ml) was added at RT to methanamine 40% in water (0.105 mol). The mixture was stirred at RT for 4 hours, then poured out into water, acidified with HCl (3N) and extracted with CH2Cl2. The organic layer was separated, dried, filtered and the solvent was evaporated. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH 97/3). The pure fractions were collected and the solvent was evaporated, yielding 1.25 g (43%) of (±)-2-chloro-α-(4-chlorophenyl)-4-(4,5-dihydro-3,5-dioxo-1,2,4-triazin-2(3H)-yl)-α,N-dimethylbenzeneacetamide (comp. 1.14).
