Procedure

5-({1-[(4-cyclobutyl-1,4-diazepan-1-yl)carbonyl]azetidin-3-yl}amino)-N-methylpyridine-2-carboxamide (34 mg, 92 μmol) was dissolved in 1:1 MeCN/water (3 ml) and formaldehyde (50 μl of a 37% wt. soln, 1.8 mmol) followed by NaBH3CN (34 mg, 0.56 mmol) were added. After 10 minutes, acetic acid (40 μl, 0.72 mmol) was added and the reaction stirred at room temperature for 16 hours. The reaction mixture was concentrated at reduced pressure and purified by FCC (DCM/MeOH/NH3 gradient, 98:2:1 to 90:10:1) giving the title compound as colourless oil (7 mg, 19%).
