实验步骤: 3-(N-Acetylamino)-3-carboethoxy-1,2,3,4-tetrahydroquinolin-2-one (0.75 g, 100M %) was suspended in 6N HCl (25 mL) and the mixture was heated to 100° C. for 3 hours. The reaction was cooled, rotoevaporated to a residue and then partitioned between water and ethyl acetate. The water was extracted with ethyl acetate (3×) and the combined ethyl acetate extracts were then washed with water (3×) and then brine (1×). Treatment with MgSO4 followed by rotoevaporation yielded 3-(R,S)-amino-1,2,3,4-tetrahydroquinolin-2-one (72% yield). The reaction was cooled partitioned between water and ethyl acetate The water was extracted with ethyl acetate (3×) the combined ethyl acetate extracts were then washed with water (3×)

实验步骤: Following General Procedure A above using N-(3,5-difluorophenylacetyl)-L-alanine (Example B) and 3-amino-1,2,3,4-tetrahydroquinolin-2-one (Example 5-A), the title compound was prepared as a mixture of diasteromers. The reaction was monitored by tlc on silica gel (Rf=0.38 in 25% ethyl acetate/hexanes) and purification was by flash chromatography using 25% ethyl acetate/hexanes as the eluant. The reaction was monitored by tlc on silica gel (Rf=0.38 in 25% ethyl acetate/hexanes) and purification
