Compound C43 was prepared according to the general procedure for the synthesis of C40 in Example 9, except that 1-(diphenylmethyl)-3-phenylazetidine (See M. C. Hillier & C-y. Chen, J. Organic Chem. 2006, 71, 7885-7887) was used instead of 1-(diphenylmethyl)-3-(4-fluorophenoxy)azetidine, and the silica gel chromatography was carried out with 100:5:1 chloroform:MeOH:concentrated aqueous ammonium hydroxide as eluant. Yield: 427 mg (contains some impurities), <3.21 mmol, <19%. LCMS m/z 134.0 (M+1). 1H NMR (400 MHz, CD3OD), product peaks only: δ 4.02 (m, 2H), 4.11 (m, 3H), 7.29 (m, 5H).
