Participants

Reaction Steps

Hydrazine (1 ml, 32 mmole) was added to a solution of 500 mg (1.34 mmole) of 2-di-n-propylamino-8-t-butoxycarbonylacetyl-1,2,3,4-tetrahydronaphthalene in 25 ml methanol and stirred at room temperature for for 24 hours. The product was isolated by concentrating the reaction mixture followed by flash chromatography, eluting with 1:1 CH2Cl2 :MeOH, and finally crystallizing from MeOH/EtOAc, m.p. 214°-216° C. Analysis: Theory: C, 72.81, H, 8.68, N, 13.41; Found: C, 73.01, H, 8.81, N, 13.27.
