実験手順

To a solution of N-methoxymethanamine hydrochloride (3.90 g) in N,N-dimethylformamide (100 mL) was added triethylamine (5.60 mL) for neutralization, and a solution of 2-[4-(cyclopropylsulfonyl)phenyl]-3-(tetrahydro-2H-pyran-4-yl)propanoic acid (11.23 g) in N,N-dimethylformamide (50 mL), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (9.60 g) and 1-hydroxybenzotriazole (6.80 g) were added under ice-cooling. The reaction mixture was warmed to room temperature and stirred overnight. The reaction mixture was diluted with ethyl acetate, and washed with water, 1N aqueous hydrochloric acid solution and saturated aqueous sodium hydrogen carbonate. The ethyl acetate layer was dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (10.2 g, yield 81%) was obtained as colorless amorphous crystals from a fraction eluted with ethyl acetate-hexane (1:1, volume ratio). MS: 382 (MH+).
