実験手順

To a mixture of 2-naphthoic acid (5.8 g, 33.7 mmol), 2-amino-N-methoxy-N-methylacetamide (Gly Weinreb amide; prepared from Boc-Gly Weinreb amide 15 as in Example 44) (3.8 g, 32.1 mmol) and DIPEA (12.0 mL, 68.9 mmol) in DCM (70 mL) was added BOP (14.9 g, 33.7 mmol) in one portion at room temperature. The resulting mixture was stirred for 1 hr then saturated NaHCO3 aqueous solution was added. The organic layer was washed with brine (5×60 mL) and 1 N HCl (2×30 mL), dried over MgSO4, filtered and concentrated under reduced pressure to give the crude product, which was used in the next reaction without further purification.
