With oxalyl dichloride;N,N-dimethyl-formamide; In dichloromethane; at 20℃; for 2h; Step 2: Preparation of tert-butyl 2-cvano-3-(3-isopropoxyphenyl)-3-oxopropanoate; A solution of <strong>[60772-67-0]3-isopropoxybenzoic acid</strong> (10.0 g, 55.5 mmol) in dichloromethane (200 mL) was consecutively treated with 2 drops of DMF and with oxalyl chloride (9.6 mL, 111 mmol). The solution was stirred at room temperature for 2 h and the volatiles were subsequently removed under reduced pressure yielding the corresponding acid chloride. Separately, a solution of tert-butylcyano acetate (13.3 g, 94.3 mmol) in THF (50 mL) was added dropwise to a solution of potassium tert-butylate (8.7 g, 77.7 mmol) in THF (300 mL). The resulting solution was stirred for 30 min. at room temperature and was subsequently cooled to 0 0C. To this solution, the acid chloride described above was added dropwise as solution in THF (60 mL). The resulting mixture was stirred for an additional 2 h at room temperature and the volatiles were subsequently removed under reduced pressure. Thereby, the maximum temperature must not exceed 40 0C. The residue was dissolved in diethylether EPO <DP n="117"/>(250 mL) and the organic solution was extracted with an aqueous potassium hydroxide solution (1%). The aqueous extracts were acidified with hydrochloric acid to pH 1, saturated with sodium chloride and extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over MgSO4 and the volatiles were removed under reduced pressure yielding tert-butyl 2-cyano-3-(3-isopropoxyphenyl)-3-oxopropanoate (10.3 g, 53%). 1H NMR (400 MHz, CDCl3) δ 14.40 (s, IH), 7.53 (d, IH), 7.45 (s, IH), 7.36 (dd, IH), 7.08 (dd, IH), 4.57 (hept., IH), 1.61 (s, 9H), 1.35 (d, 6H).

After cooling to room temperature, the aqueous system was extracted with diethylether and the combined organic layers were discarded. By addition of concentrated hydrochloric acid and saturated with sodium chloride, the pH value of the aqueous layer was adjusted to 5. The aqueous layer was then extracted with cyclohexane. The combined organic extracts were washed with brine, dried over MgSO4 and the solvents were evaporated off. The resulting solid was dissolved in methanol (40 mL) and water (500 mL) was added under vigorous stirring. The precipitate thus formed was collected by filtration and dried under reduced pressure yielding 3-isopropoxybenzoic acid (24 g, 29%). ES-MS m/z 179.1 (M-H+); HPLC RT (min) 1.97 {method (H) }.
