YieldReaction ConditionsOperation in experiment
89% With potassium carbonate In N,N-dimethyl-formamide at 35℃; for 17h; 88.A Step A: A mixture of methyl 2-chlorobenzoxazole-4-carboxylate (620 mg, 2.96 mmol) and (3S,5S)-3,5-dimethylmorpholine (341 mg, 2.96 mmol) and potassium carbonate (1.0 g, 7.4 mmol), in DMF (15 mL), was stirred in a 35° C. oil bath. After 17 h, the reaction mixture was cooled to ambient temperature, diluted with H2O (50 mL) and extracted with EtOAc (2×30 mL). The combined organic layers were washed with H2O (3×20 mL), brine (20 mL), dried (Na2SO4), and concentrated under reduced pressure. Methyl 2-((3 S,5S)-3,5-dimethylmorpholino)benzoxazole-4-carboxylate (770 mg, 89%) was obtained as an amber oil. 1H NMR consistent.

63% Step A: To a solution of <strong>[120737-78-2]tert-butyl 2-methylpiperazine-1-carboxylate</strong> (340 mg, 1.70 mmol) in THF (5 mL) was added sodium hydride (60%, 82 mg, 2.04 mmol). The reaction mixture was stirred at room temperature for 5 min, then methyl 2-chlorobenzoxazole-4-carboxylate (300 mg, 1.41 mmol) in THF (5 mL) was added to the reaction mixture. The reaction mixture was stirred at room temperature for 19 h. The mixture was concentrated under reduced pressure and the resulting residue was purified by column chromatography (silica gel, 20% EtOAc in hexane) to afford methyl 2-(4-(tert-butoxycarbonyl)-3-methylpiperazin-1-yl)benzoxazole-4-carboxylate (336 mg, 63%) as yellow solid. MS consistent.

Stage #1: (+)-(S,S)-3,5-dimethylmorpholine With sodium hydride In 1,2-dimethoxyethane for 0.166667h; Stage #2: 2-chloro-benzooxazole-4-carboxylic acid methyl ester In 1,2-dimethoxyethane at 0 - 20℃; for 72h; 75.A Step A: To a solution of (3S,5S)-dimethylmorpholine (209 mg, 1.82 mmol) in 1,2-dimethoxyethane (10 mL) was added NaH(60% suspension in mineral oil, 146 mg, 3.64 mmol). After 10 min the reaction mixture was cooled to 0° C. and methyl 2-chlorobenzoxazole-4-carboxylate (500 mg, 2.36 mmol) was added portion-wise over 5 min. After 10 min, the reaction mixture was warmed to ambient temperature and allowed to stir for 3 days. The reaction mixture was quenched with CH3OH (10 mL) and then dry loaded onto silica gel (4.5 g). Purification by chromatography (silica gel, 0 to 20% EtOAc in hexanes) gave a 1:1 mixture of methyl 2-((3S,5S)-3,5-dimethylmorpholino)benzoxazole-4-carboxylate and methyl 2-oxo-2,3-dihydrobenzoxazole-4-carboxylate (312 mg, 59%) as an off-white solid.
