Procedure
5-{4-[(1-Cyclobutyl-4-piperidinyl)methyl]-1-piperidinyl}-2-pyridinecarbonyl chloride hydrochloride (may be prepared as described in Example 11, step 1) was dissolved in dichloromethane (10 ml) and added dropwise to a stirred solution of methylamine (1.57 ml of a 2M solution in tetrahydrofuran) in dichloromethane (10 ml) cooled to 0° C. over 1 h. The reaction was allowed to stir for a further 3 h before the mixture was evaporated. Chromatography (silica gel, eluting with methanol/dichloromethane, 0-20%) afforded the title compound (E11) (0.13 g). MS electrospray (+ion) 371 (MH+).1H NMR δ (CDCl3): 8.14 (1H, d, J=2.8 Hz), 8.01 (1H, d, J=8.8 Hz), 7.75 (1H, m), 7.19 (1H, dd, J=2.8, 8.8 Hz), 3.80 (2H, m), 3.00 (4H, m), 2.82 (3H, m), 2.19-1.21 (21H, m obscured by H2O)
