Procedure: MsCl (2.48 mL, 32.1 mmol) was added slowly to a solution of 4-benzyloxy-butan-1-ol (5.26 g, 29.2 mmol) and Et3N (6.1 mL, 43 mmol) in CH2Cl2 (100 mL) at 0° C. (bath temp). The reaction mixture was stirred at rt for 2 h and then quenched with H2O (100 mL). The aqueous layer was extracted with CH2Cl2, dried (MgSO4), and concentrated in vacuo to give the title compound as a colorless liquid: yield 7.5 g (99%). quenched with H2O (100 mL) The aqueous layer was extracted with CH2Cl2 dried (MgSO4) concentrated in vacuo

Procedure: Alkylation reaction of 3-hydroxybenzaldehyde (11) with 4-(benzyloxy)butyl methanesulfonate following the method used in Example 149 gave 3-(4-(benzyloxy)butoxy)benzaldehyde (137) as a clear oil. Yield (1.5 g, 80%): 1H NMR (400 MHz, CDCl3) δ 9.97 (s, 1H), 7.42-7.46 (m, 2H), 7.33-7.38 (m, 5H), 7.28-7.31 (m, 1H), 7.14-7.18 (m, 1H), 4.53 (s, 2H), 4.04 (t, J=6.4 Hz, 2H), 3.56 (t, J=6.4 Hz, 2H), 1.88-1.98 (m, 2H), 1.80-1.87 (m, 2H).

Procedure: Methanesulfonyl chloride (1 mL, 13.3 mmol) was added to a cooled (0° C.) solution of 4-(benzyloxy)butan-1-ol (2 g, 11.1 mmol) and triethylamine (1.9 mL, 13.3 mmol) in DCM (20 mL) and it was stirred at 0° C. for 1 h. HCl (1M) was added to the reaction mixture and the aqueous layer was extracted with DCM (2×). The organics were combined, dried over sodium sulfate, and evaporated to dryness to afford 4-(benzyloxy)butyl methanesulfonate as a yellow oil. LCMS [M+1]+ 259.5. the aqueous layer was extracted with DCM (2×) dried over sodium sulfate evaporated to dryness
