Step 1: ethyl 2-(2-((3-(trifluoromethyl)benzoyl)imino)-4,5,6,7-tetrahydrobenzo[d]thiazol-3(2H)-yl)acetate To a solution of 4,5,6,7-tetrahydrobenzo[d]thiazol-2-amine (200 mg, 1.297 mmol) in tetrahydrofuran (4.3 mL) were added 3-(trifluoromethyl)benzoyl chloride (324 mg, 1.56 mmol) and potassium carbonate (359 mg, 2.59 mmol). The reaction mixture was stirred at 80 C. for 5 hours and then concentrated under reduced pressure. To the resulting intermediate (0.43 mmol) were added N,N-dimethylformamide (1.5 mL) and ethyl bromoacetate (93 mg, 0.559 mmol). The reaction mixture was stirred at 80 C. for 3 hours and then cooled to room temperature. The reaction mixture was quenched with water and then extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, filtered, and then evaporated. The residue was purified with silica gel column chromatography (n-hexaneethyl acetate=41) to give 103 mg of the titled compound as a white solid (Yield: 58%). 1H NMR (CDCl3, 400 MHz) delta 12.40 (brs, 1H), 8.54 (s, 1H), 8.43 (d, 1H), 7.71 (d, 1H), 7.54 (dd, 1H), 4.90 (s, 2H), 4.24-4.30 (m, 2H), 2.59 (brs, 2H), 2.50 (brs, 2H), 1.87-1.92 (m, 4H), 1.30 (t, 3H).

EXAMPLE 15 Preparation of Ethyl N-(4,5,6,7-Tetrahydrobenzothiazol-2-yl)carbamate 2-Amino-4,5,6,7-tetrahydrobenzothiazole (12.3 grams; 0.08 mol) dissolved in pyridine (50 ml.) was charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and addition funnel. Ethyl chloroformate (12 ml; 0.11 mol) was added dropwise to the reaction mixture with stirring and cooling. After the addition was completed the reaction mixture was allowed to warm to room temperature and stirring was continued for a period of about 1 hour. After this time the reaction mixture was poured into ice water (50 mol.) to form a precipitate. The precipitate was recovered by filtration, washed with water four times dried and recrystallized from ethanol to yield the desired product ethyl N-(4,5,6,7-tetrahydrobenzothiazol-2-yl)carbamate; (16.7 grams); melting point 182-184 C. The structure of the product was verified by infrared and NMR spectroscopy., 2933-29-1
