Followed the same procedure as that of step 2 in Example 91 with the use of (R)-2-(4-hydroxy-phenoxymethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (150 mg, 0.5 mmol) and 4-trifluoromethyl-benzyl bromide (145 mg, 0.6 mmol) to afford title product (135 mg, 60% yield); LCMS; 100% APCI+, Calcd: +451.49. Found m/z: 452.3 (M+1). 1H NMR (400 MHz, CDCl3); δ 1.47 (s, 9H), 1.80-2.09 (m, 4H), 3.28-3.46 (m, 2H), 3.69-3.91 (m, 1H), 4.02-4.18 (m 2H), 5.07 (s, 2H), 6.87 (s, 4H), 7.53 (d, J=8.4 Hz, 2H), 7.63 (d, J=8.0 Hz, 2H).
