実験手順

Ethyl formate (1.2 mL, 15.0 mMol) was added to a round bottom flask containing (1R)-1-cyclohexyl-ethylamine Compound 17a (1.27 g, 10 mMol) at 0° C. and the mixture was stirred at r.t. for 15 hrs. Excess ethyl formate was removed in vacuo to obtain N-[(1R)-1-cyclohexyl-ethyl]-formamide Compound 17b (1.55 g) as a white solid, which was used in the next step without purification. MS m/z 156 (MH+).
