Acetoxyacetyl chloride → HCID 86675917, compound

Participants

Reaction Steps

To a cold solution of N-(4-fluoro-3-methoxybenzyl)-2-methyl-6-(5-(piperidin-4-yl)-4,5-dihydroisoxazol-3-yl)pyrimidine-4-carboxamide hydrochloride (1.8 g, 3.87 mmol, Preparation #K.1) in dichloromethane (20 mL) were added TEA (3.3 mL, 23.2 mmol) and acetoxyacetyl chloride (0.5 mL, 4.65 mmol). The reaction mixture was slowly warmed to RT and stirred for about 10 min. The reaction mixture was diluted with water (10 mL) and the product was extracted with DCM (2×20 mL). The combined organic layers were washed with water (1×25 mL) followed by brine (1×50 mL). The organic layer was dried over sodium sulphate and concentrated under reduced pressure to afford 2-(4-(3-(6-(4-fluoro-3-methoxybenzylcarbamoyl)-2-methylpyrimidin-4-yl)-4,5-dihydroisoxazol-5-yl)piperidin-1-yl)-2-oxoethyl acetate as a brown solid 1.8 g (90%).
