Triethylamine → Benzamide

Participants

Reaction Steps

A solution of 3,4-dichlorobenzoyl chloride Compound 1e (0.25 mmol, 0.06 g) in THF (1 mL) was added dropwise over 2 min to a solution of Compound 2c (0.2 mmol, 0.05 g) and Et3N (0.4 mmol, 0.06 mL) in THF (4 mL) at 0° C. The resulting suspension was allowed to warm to r.t. overnight, then made basic with a 2N NaOH-solution and extracted with EtOAc (10 mL). The aqueous layer was extracted with EtOAc (2×10 mL). The organic layers were washed with brine, then dried over Na2SO4 and filtered. The solvent was removed in vacuo to yield 3,4-dichloro-N-(4-{2-[methyl-(tetrahydro-pyran-4-yl)-amino]-ethyl)}-phenyl)-benzamide Compound 2d as a yellow solid. The product was purified by preparative TLC (10:1 EtOAc:MeOH) (0.06 g, 73%). MS m/e 407 (M+H, 100%);
