実験手順: To 3-trimethylsilanylethynyl-benzaldehyde 73(a1) from step 1a in methanol (540 mL, 0.3 M) was added KF (18.8 g, 324 mmol), and the resulting mixture stirred at 22° C. for 6 hours. After cooling to 0° C., NaBH4 (6.13 g, 162 mmol) was carefully added over 0.5 hours. Aqueous saturated NH4Cl was carefully added and the volatiles were removed in vacuo. Ethyl acetate (200 mL) was added, and the organic phase was washed with water and a saturated aqueous NaCl solution, dried over MgSO4 and filtered. The volatiles were removed in vacuo to afford crude (3-ethynyl-phenyl)-methanol 73(a2). After cooling to 0° C. the volatiles were removed in vacuo Ethyl acetate (200 mL) was added the organic phase was washed with water a saturated aqueous NaCl solution, dried over MgSO4 filtered The volatiles were removed in vacuo

実験手順: To a mixture of 1-bromo-3-methoxymethoxymethyl-benzene (3.0 g, 13 mmol) described in Manufacturing Example 214-1-1, trimethylsilylacetylene (2.6 g, 26 mmol), N,N-diisopropylethylamine (3.4 g, 26 mmol), copper (I) iodide (500 mg, 2.6 mmol), and 1-methyl-2-pyrrolidone (30 mL) was added tetrakis(triphenylphosphine)palladium (0) (1.5 g, 1.3 mmol), which was stirred for 15 minutes at 60° C. This mixture was partitioned into ethyl acetate and water. The organic layer was separated and concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (heptane:ethyl acetate=8:1) to obtain a mixture of (3-methoxymethoxymethyl-phenylethynyl)-trimethyl-silane and 1-bromo-3-methoxymethoxymethyl-benzene (3.0 g of mixture, including approximately 30% (3-methoxymethoxymethyl-phenylethynyl)-trimethyl-silane). Tetrabutylammonium fluoride (2 mL, 1 M tetrahydrofuran solution) was added to a tetrahydrofuran (20 mL) solution of this mixture, which was stirred for 15 minutes at room temperature. The reaction solution was partitioned into ethyl acetate and water. The organic layer was separated and concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (heptane:ethyl acetate=20:1) to obtain 1-ethynyl-3-methoxymethoxymethyl-benzene (470 mg). To a methanol (10 mL) solution of this 1-ethynyl-3-methoxymethoxymethyl-benzene (470 mg, 2.6 mmol) was added 5 N hydrochloric acid, which was stirred for 25 minutes at 70° C. The reaction solution was partitioned into ethyl acetate and water. The organic layer was separated and concentrated under a reduced pressure to obtain the title compound (350 mg, 20%). The reaction solution was partitioned into ethyl acetate and water The organic layer was separated concentrated under a reduced pressure

NH silica gel was added to the reaction solution, and the solvent was evaporated under a reduced pressure. The crude product that had adsorbed to the NH silica gel was purified by NH silica gel column chromatography (heptane:ethyl acetate=2:1, then 1:1, then ethyl acetate) to obtain the title compound (110 mg, 51%).
