YieldReaction ConditionsOperation in experiment
75% Compound 3Step i :(R)-3-Boc-amino-5-(carboxymethyl)-2,3-dihydro-1 ,5-benzothiazepin-4(5H)-one, 3-1 , (352 mg, 1.0 mmol) was dissolved in CH2CI2 (5 mL) and treated with EDC (232 mg, 1.5 mmol), HOBt (202 mg, 1.5 mmol) and DIPEA (520 μL, 3.0 mmol). The reaction was stirred for 5 minutes before (R)-1 , 2,3,4-tetrahydronaphthalamine (176 μL, 1.2 mmol) was added. The reaction was stirred for 16 hrs at room temperature before being partitioned between ethyl acetate (100 mL) and 10% citric acid (20 mL). The organic phase was washed with 10 % citric acid (2 x 20 mL), saturated aqueous NaHCO3 (3 x 20 mL), and brine (1 x 20 mL). <n="57"/>Attorney Docket No. L80003375WO The organic fraction was dried over anhydrous MgSO4, filtered, and the volatiles removed under reduced pressure. The resulting residue was purified by silica gel chromatography, eluting with a 10-100 % THF/hexanes gradient to provide 3-2a as a white solid (360 mg, 75 % yield).
