実験手順

A solution of (R)-tert-butyl 5-(1-(tert-butyldimethylsilyloxy)-2-(1-(3-formylphenyl)-2-methylpropan-2-ylamino)ethyl)-2-oxo-1,2-dihydroquinolin-8-yl carbonate (Example 275, step g) (0.42 g) in methanol (15 mL) was treated with ammonia (35% aqueous) (2 mL). The reaction mixture was allowed to stand for 3 hours at 20° C. The solvent was removed under a stream of nitrogen and the residue was partitioned between ethyl acetate and brine. The aqueous layer was extracted with ethyl acetate and the combined organics dried over sodium sulphate, filtered and the solvent evaporated under reduced pressure to afford the subtitled compound. Yield 0.34 g.
