Triethylamine → HCID 53886633, compound

Participants

Reaction Steps

To an ice-cooled solution of (R)-2-amino-8-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydronaphthalene (110 mg, 0.43 mmol) and triethylamine (90 μL, 0.65 mmol) in methylene chloride (15 mL) was added dropwise 2-ethoxybenzoyl chloride (84 mg, 0.45 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 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: 110 mg (64%) of the title compound as white solid: [α]21D −36° (c 1.0, chloroform); EIMS (70 eV) m/z (relative intensity) 393 (15, M+). The hydrochloride salt was precipitated out of diethyl ether and 110 mg (59% yield) of white crystals were isolated; mp sinters at 176° C.
