Reaction Steps
3-Phenoxybenzoic acid (1.0 g, 4.7 mmol) was dissolved in thionyl chloride (15 mL) and heated at reflux for 1 h. The excess of thionyl chloride was evaporated in vacuo, the residue was treated with toluene and again the solvent was removed in vacuo. Crude acid chloride (99 mg, 0.42 mmol) was dissolved in methylene chloride (5 mL) and added dropwise to an ice-cooled solution of (R)-2-amino-8-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydronaphthalene (99 mg, 0.41 mmol) and triethylamine (83 μL, 0.42 mmol) in methylene chloride (20 mL). After the addition, the reaction was allowed to stir at ambient temperature for 15 min and was then washed with water. 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: 120 mg (68%) of the title compound as an oil. The oil crystallized from diethyl ether/hexane: mp 136-137° C.; [α]21D −9.0° (c 1.0, chloroform); EIMS (70 eV) m/z (relative intensity) 441 (31, M+).
