Intermediate 30: tert-butyl l-(4-chlorophenyl)-3-hvdroxypropylcarbamateDi-tert-butyl dicarbonate (0.705 g, 3.23 mmol) was added to 3-amino-3-(4- chlorophenyl)propan-l-ol (Intermediate 29) (0.500 g, 2.69 mmol) in DCM (30 mL) at 220C. The resulting solution was stirred at 22 0C for 2 hours. The mixture was concentrated and the residue was purified by flash silica chromatography, elution gradient 0 to 4% (10:1 MeOH/conc. NH3 (aq)) in DCM. Pure fractions were evaporated to dryness to afford tert-butyl l-(4-chlorophenyl)-3-hydroxypropylcarbamate (0.759 g, 99 %) as a white solid.IH NMR (399.902 MHz, CDC13) delta 1.43 (9H, s), 1.81 (IH, m), 2.04 (IH, m), 2.74 (IH, br.s), 3.69 (2H, m), 4.88 (IH, br.s), 5.04 (IH, d), 7.23 (2H, d), 7.32 (2H, d).
