Reaction Steps

To an ice-cooled solution of (R)-2-amino-8-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydronaphthalene (110 mg, 0.45 mmol) and triethylamine (93 μL, 0.67 mmol) in methylene chloride (25 mL) was added dropwise 4-chlorobenzoyl chloride (83 mg, 0.47 mmol) in methylene chloride (5 mL). After the addition, the reaction was allowed to stir at ambient temperature for 15 min and was then washed with diluted aqueous sodium hydrogen carbonate. The phases were separated and the organic phase was dried (Na2SO4), filtered and evaporated in vacuo to give a crude product which was purified on a silica gel column using chloroform/ethanol saturated with NH3 (100:3) as the eluent. Yield: 97 mg (56%) of the title compound as white crystals: mp 204-205° C.; [α]21D -46° (c 1.0, chloroform); EIMS (70 eV) m/z (relative intensity) 383 (19, M+).
