Participants

Reaction Steps

To a solution of 2-butyl-6-isopropylquinazolinone (55.6 mg; 0.228 mmol) (Example 8) in dry DMF (1.5 mL) was added NaH, 80% oil dispersion, (11.8 mg; 1.5 eq). The reaction mixture was allowed to stir for 30 min. under N2. To this was added a solution of N-triphenylmethyl-5-(4-fluoro-4'-bromomethyl-biphen-2-yl)tetrazole (crude) in dry DMF (1.5 mL). The reaction was stirred under N2 for 3 hrs. then quenched with saturated NH4Cl solution. The solvent was removed at high vacuum, replaced by EtOAc, and the insoluable salts filtered off. The product was purified by flash chromatography on a silica column eluting with Hex/EtOAc (35:1) to afford 94.5 mg (56%) of the titled compound. Characteristic peaks 1H-NMR (300 MHz, CDCl3) δ 0.87 (t, 3H), 1.30 (d, 6H), 1.68 (m, 2H), 2.63 (t, 2H), 3.05 (q, 1H), 5.28 (s, 2H), 8.13 (s, 1H).
