Yield	Reaction Conditions	Operation in experiment
95 - 100%	With sodium iodide; In N,N-dimethyl-formamide; acetonitrile; for 10.0h;Heating / reflux;	Into a 500 mL 3-neck round bottom flask was added 10 g (61.75 mmol) of 2-bromomethyl, 3-methoxy methyl benzoate, 4.0 g (81.6 mmol) of NaCN, 0.30 g (2 mmol) of NaI, 100 mL of CH3CN, and 50 mL of DMF. The reaction mixture was heated and refluxed for 10 hours. The precipitate (NaBr) was filtered off, and the solution was concentrated on an evaporator. 300 mL of water and 200 mL of ether were added and then shaken in a separatory funnel. The water was extracted twice with 100 mL of ether. The ether fractions were dried over MgSO4, and concentrated to yield methyl 3-methoxy-2-cyanomethylbenzoate (95-100% yield). This ester (0.053 mmol, 10.51 g) was stirred vigorously in 100 mL of CH3OH. Ba(OH)2 H2O (0.079 mmol, 14.97 g) was added and the mixture stirred at room temperature overnight. The CH3OH was removed on a rotary evaporator. 150 mL of water, 200 mL of CH2Cl2, and 50 mL of 6N HCl were added, and then stirred in a flask to dissolve all residues. The mixture was transferred to a separatory funnel, acidified with 6N HCl to pH 1-2. The CH2Cl2 phase was separated and the aqueous phase extracted twice with 50 mL of CH2Cl2. The CH2Cl2 extracts were combined, dried over MgSO4 and charcoal, filtered, and evaporated to yield 8.8 g of a white solid, 2-cyanomethyl-3-methoxybenzoic acid, (87%). Methyl 3-methoxy-2-cyanomethylbenzoate: 1H NMR (CDCl3, 300 MHz) delta (ppm): 7.6 (d, 1H), 7.4 (t, 1H), 7.1 (d, 1H), 4.18 (s, 2H), 3.94 (s, 3H), 3.926 (s, 3H). TLC (1:1 ethyl acetate: hexane) 0.55. 2-Cyanomethyl-3-methoxybenzoic acid: 1H NMR (300 Mhz, CDCl3) delta (ppm): 7.55 (d, 1H), 7.45 (t, 1H), 7.3 (d, 1H), 4.121 (d, 2H), 3.91, (s, 3H). TLC (1:1 ethyl acetate: hexane
