Procedure:
To a solution of tert-butyl thiazol-4-ylcarbamate (13.0 g, 64.9 mmol) in DMF (150 mL) was added Cs2CO3 (42.3 g, 130 mmol) and 1-(chloromethyl)-4-methoxybenzene (12.1 g, 78.0 mmol, Spectrochem).

Procedure:
A solution of 49.6 g (0.40 mole) dimethyl methylphosphonate (Aldrich) in 500 ml dry tetrahydrofuran was cooled to -78° in a dry nitrogen atmosphere. To the stirred phosphonate solution was added 188 ml of 2.34 M n-butyllithium in hexane solution (Alfa Inorganics, Inc.) dropwise over a period of 40 minutes at such a rate that the reaction temperature never rose above -65°. After an additional 5 minutes stirring at -78°, 31.2 g (0.20 mole) methylcyclohexylacetate was added dropwise at a rate that kept the reaction temperature less than -70° (20 minutes). After 1.0 hour at -78° the reaction mixture was allowed to warm to ambient temperature, neutralized with 25 ml acetic acid and rotary evaporated to a white gel. The gelatenous material was taken up in 75 ml water, the aqueous phase extracted with 100 ml portions of chloroform (3x), the combined organic extracts were backwashed (50 cc H 2 O), dried (MgSO4), and concentrated (water aspirator) to a crude residue and distilled, b.p. 160°-162° (0.2 mm) to give dimethyl 2-oxo-3-cyclohexylpropylphosphonate (2h).

Procedure:
In a sulfonation flask, 50.2 g (0.32 mol) of methyl 2-aminothiophene-3-carboxylate are added to 480 ml of chloroform and 320 ml of water. Then 40.5 g (0.35 mol) of thiophosgene and 1000 ml of saturated aqueous sodium bicarbonate solution are added simultaneously in 40 minutes under stirring. The stirring continued for 1 h at room temperature and then the organic phase is separated. The water phase is extracted twice with chloroform and the organic phase dried over sodium sulfate. After removal of the chloroform in the water-jet vacuum 61.3 g of a dark oil is obtained, which is further purified by column chromatography over silica gel (eluant: ethyl acetate/hexane=1:5). 41.5 g of methyl 2-isothiocyanatothiophene-3-carboxylate are obtained in the form of a brown powder having a melting point of 63-65° C.
