Procedure
To a solution of N-[2-[3-(1-(2-cyanoethyl)-5-tetrazolyl)-benzyloxy]-1(S)-cyanoethyl]-3-methyl-Nα-phenyl-L-phenylalaninamide (prepared according to examples 1(g) and 7 using intermediate of Example 1(e)), 160 mg, 0.30 mmol) in CH2Cl2 (10 mL) is added DBU (0.22 mL, 1.5 mmol) in one portion, and the solution is stirred at room temp. for 2 h., after which time the solution is washed with 1 N HCl (30 mL), brine (30 mL), dried (MgSO4), evaporated, and chromatographed (2% MeOH/CH2Cl2, 0 to 0.05% acetic acid) to yield N-[2-[3-(5-tetrazolyl)-benzyloxy]-1(S)-cyanoethyl]-3-methyl-Nα-phenyl-phenylalaninamide, as an off-white solid; m.p. 120-122° C.
