A solution of 2-(2,4-dimethoxy-benzyl)-4-(2-dimethylamino-ethoxy)-2,3-dihydro-1H-isoindole (170 mg, 0.48 mmol) in trifluoroacetic acid (0.5 mL) and anisole (0.5 mL) was heated at 150° C. under microwave irradiation for 10 minutes. The mixture was diluted with ethyl acetate and extracted twice with water. The combined aqueous extracts were concentrated to give the title compound as a purple oil (240 mg, including residual TFA and/or water). 1H NMR (methanol-d4) 7.42 (1H, t), 7.07 (1H, d), 7.04 (1H, d), 4.64 (4H, br.s), 4.47-4.44 (2H, m), 3.65-3.63 (2H, m), 3.01 (6H, s). MS: [M+H]+ 207.
