実験手順

A solution of 2-(2-hydroxyethyl)-4-(1-methylcarbamoyl-2-naphthalen-2-ylethyl)piperazine-1-carboxylic acid tert-butyl ester, 60, (4.4 g, 10 mmol), acetic anhydride (13 mL), pyridine (1 mL) and N,N-dimethylaminopyridine (0.25 g) in dichloromethane (50 mL) is stirred for 1.5 hours. The solution is then extracted with water and 1 n HCl. The organic phase is dried, concentrated in vacuo, and the resulting crude product purified over silica gel (EtOAc/hexane 1:3 then 1:1) to afford the desired product.
