Procedure:
2-((2-Aminothiazol-5-yl)thio)propan-1-ol (101 mg, 0.53 mmol) was dissolved in N,N-dimethylformamide (5 mL). Thereafter, imidazole (72 mg, 1.06 mmol) and t-butyldimethylsilyl chloride (100 mg, 0.64 mmol) were added to the above obtained solution, and the thus obtained mixture was then stirred at room temperature for 14.5 hours. Thereafter, the reaction solution was diluted with water, and was then extracted with ethyl acetate. The organic layer was washed with water and brine, and was then dried over anhydrous magnesium sulfate, followed by concentration in vacuo. The obtained residue was purified by preparative thin-layer chromatography (chloroform:methanol=10:1) to obtain 5-((1-((t-butyldimethylsilyl)oxy)propan-2-yl)thio) thiazole-2-amine (141 mg, 87%) in the form of a yellow oily product.

Procedure:
Under an anhydrous condition, a solution containing 2.72 g of 3-acetoxymethyl-7-amino-3-cephem-4-carboxylic acid and 1.56 g of 4,6-diamino-1-methyl-2-(1H)pyrimidinethione suspended in 20 ml of dry acetonitrile was cooled to 0° C.; and 3.6 ml of boron trifluoride diethylether was added. The temperature of the reaction solution was increased to a room temperature, e.g., 18°-20° C.; the solution was stirred for three hours; and then 10 ml of methyl alcohol was added. The resultant solution was stirred for 10 minutes and was added with 30 ml of ice water. The pH of the solution was adjusted to 7.1 by adding aqueous ammonia solution After concentration under a reduced pressure, e.g., about 20 mmHg, the solution was adjusted to pH 3.7 with 2N-aqueous hydrochloric acid; and allowed to stand at a room temperature for 24 hrs. The precipitates resulted from the reaction solution were filtered, washed with 10 ml of distilled water and with 10 ml of methyl alcohol, and dried to give 2.69 g of the title compound as a solid.

Procedure:
To a stirred solution of phenylmagnesium bromide [from bromobenzene and magnesium in dry tetrahydrofuran] was added 2,2-dimethyl-7-(2-dimethylaminoethoxy)-chroman-4-one in dry THF and the resulting solution was boiled under reflux for 2 weeks. The cooled reaction mixture was decomposed with 2.5 N hydrochloric acid and the organic layer separated and dried (magnesium sulphate). Removal of the solvent gave a yellow oil which was chromatographed on silica in 3% ether--97% light petroleum (b.p. 60°-80°) gave the title compound as a colourless oil. Dissolution in dry ether and passage of dry hydrogen chloride through the solution gave the hydrochloride salt, m.p. 186.5°-187.5°. An analogous procedure yielded 7-(2-N-benzyl-N-methyl-aminoethoxy)-4-(4-fluorophenyl)-2, 2-dimethyl-2H-chromene as a colourless oil.
