According to the precedure described in Nakamura et al. (J.A.C.S. 1985, 107 p2138), intermediate 5d (0.001 mol) was added to a solution of KOH (0.03 g) in CH3OH (7ml) and tetrahydrofuran (3 ml). The mixture was stirred at 100° C. for 4 hours, yielding [S-(R*,R*)]-2,4-dihydro-2-(2-hydroxy-1-methylpropyl)-4-[4-[4-(4-methoxyphenyl)-1-piperazinyl]phenyl]-3H-1,2,4-triazol-3-one (interm. 5c).
