Procedure

To a solution of 1-[3-fluoro-4-[[(3S)-3-methyl-1,1-dioxo-6-phenyl-thiazinan-2 yl]methyl]phenyl]piperidin-4-ol Stereoisomer A (200 mg, 0.46 mmol, prepared as described in Example 5), tetrazole (36 mg, 0.51 mmol) and triphenylphosphine (135 mg, 0.51 mmol) in dichloromethane (2.5 mL) was added diisopropyl azodicarboxylate (103 mg, 0.51 mmol) dropwise and the reaction was stirred at r.t. for 16 hours. The reaction was partitioned between water and dichloromethane and the organic layer was concentrated and purified by preparative HPLC to give (3S)-2-[[2-fluoro-4-[4-(tetrazol-1-yl)-1-piperidyl]phenyl]methyl]-3-methyl-6-phenyl-thiazinane 1,1-dioxide Stereoisomer A (57.4 mg, 0.12 mmol, 26% yield) as a white solid. 1H NMR (400 MHz, DMSO) δ 8.99-8.96 (s, 1H), 7.49-7.43 (m, 2H), 7.43-7.29 (m, 4H), 6.89-6.82 (m, 1H), 6.82-6.75 (m, 1H), 5.18-5.07 (m, 1H), 4.50-4.36 (m, 2H), 4.33-4.25 (m, 1H), 4.16-4.03 (m, 1H), 3.87-3.76 (m, 2H), 3.10-2.98 (m, 2H), 2.47-2.37 (m, 1H), 2.31-2.23 (m, 2H), 2.19-2.04 (m, 3H), 1.89-1.73 (m, 1H), 1.70-1.59 (m, 1H), 1.13-1.06 (d, J=6.8 Hz, 3H); LCMS [M+1]+=485.2.
