Sodium Carbonate → HCID 59382310, compound

Participants

Reaction Steps

A solution of 4-methoxybenzylamine (2.4 g, 17.6 mmol) in acetone (110 ml) was added dropwise to a mixture of 1,2-bis-bromomethyl-4-chloro-5-methoxy-benzene (assumed theoretical, 17.6 mmol) and Na2CO3 (12 g, 114 mmol) in acetone/water (10 ml:12.5 ml) then stirred at room temperature for 2 hours and concentrated in vacuo. The crude material was dissolved in ethyl acetate and extracted with 2N HCl. The aqueous layer was neutralized with sodium carbonate, extracted with ethyl acetate (×2), dried (MgSO4) and evaporated under vacuum to give 5-chloro-6-methoxy-2-(4-methoxy-benzyl)-2,3-dihydro-1H-isoindole (0.8 g, 2.6 mmol) as a brown gum. MS: [M+H]+ 304
