Step A In a manner similar to the methods described in Example 112a Step A. Step B., and Step C., 3-ethyl-3-oxetanemethanol (TCI-US) (3.5 g, 30 mmol) was reacted with triethylamine (6.6 g, 60 mmol) and treated with NaCN (2.2 g, 46 mmol) in anhydrous dimethyl sulfoxide at 130° C., followed by the reaction with DIBAL (1 M in heptane, 27 mL, 27 mmol) in dichloromethane at 0° C. to give (3-ethyl-oxetan-3-yl)-acetaldehyde as a light yellow oil (Yield: 2.5 g, 26% for three steps).
