Procedure:
To a solution of 2-mercaptobenzophenone (2.3 g, 7.4 mmol) in diethyl ether (10 mL) was added dropwise diethyl azodicarboxylate (0.65 g, 3.7 mmol). The solution was stirred for 5 minutes at room temperature, then diluted with benzene (40 mL) and refluxed for 16 hours. The solution was cooled and concentrated in vacuo leaving a yellow liquid. The crude product was purified using silica gel chromatography (75% hexane/25% ethyl acetate) to give the title compound as a yellow foam (0.8 g, 50%);

Procedure:
To a solution of 2-amino-5-picoline (5 g) in acetic acid (40 mL) at r.t. was added bromine (2.6 mL) slowly. After 1 h, the acid was neutralized by the careful addition of sodium hydroxide (10N) at 0°0 C. The resulting orange precipitate was dissolved in ether and washed successively with saturated potassium carbonate, saturated Na2S2O3 and brine, dried and concentrated. Flash chromatography (eluting with hexane/ethyl acetate, 3:2 v/v) of the residual solid provided the title compound as a pale yellow solid (7.1 g).

Procedure:
A total of 144.2 grams (1.2 mol) of 2-(2-methoxyethoxy)ethanol, 400 grams (4.4 mol) of dimethyl carbonate and 3 grams (0.05 mol) of sodium methoxide were combined in a 1-liter 3-neck round bottom flask equipped with a 14 inch distillation column, distillation head, and magnetic stirbar. The system was evacuated and purged three times with nitrogen using a Firestone valve, and left under a constant nitrogen atmosphere. After a period of 1.5 hours at reflux (kettle temperature 84° C.), methanol (boiling point 64° C.) was slowly removed overhead to drive the equilbrium. A total of 49.8 grams of methanol was removed over a period of 3 hours, after which time the stopcock was closed and the reaction mixture was allowed to reflux overnight. The mixture was then cooled to room temperature, filtered and charged (429 grams) to a 500 milliliter round bottom flask equipped with a distillation head and magnetic stirbar. Excess dimethyl carbonate (boiling point 90° C.) was removed overhead. The flask was then cooled, put under vacuum (10-11 mm Hg , and methyl 2-(2-methoxyethoxy)ethyl carbonate removed overhead (boiling point 115°-125° C.). A total of 193 grams (ca. 90% yield) was obtained. Gas chromatography analysis of this material showed 97.74% purity (remainder was 2-(2-methoxyethoxy)ethanol).
