Procedure

5-(6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yloxy)-N-(3-(trifluoromethyl)phenyl)-1H-indole-1-carboxamide (140 mg, 0.320 mmol) is suspended in 1,2-dichloroethane (5 mL), and formaldehyde (50 μl, 0.672 mmol) and acetic acid (360.629 mmol) and sodium triacetoxyborohydride (139 mg, 0.656 mmol) are added and the mixture heated to 60° C. overnight. The reaction is cooled to rt, diluted with water, brine and DCM. The organic phase is removed, dried, and concentrated to an oil that is purified via FCC (0-10% NH3/MeOH:DCM) to obtain 5-(6-methyl-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yloxy)-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide. MS (ESI) m/z 454.95 (M+1); 1H NMR (400 MHz, DMSO-d6) δ ppm 10.38 (s, 1 H), 8.56 (s, 1 H), 8.27 (d, J=9.09 Hz, 1 H), 8.09-8.13 (m, 2 H), 7.96 (s, 1 H), 7.65 (t, J=8.08 Hz, 1 H), 7.48-7.51 (m, 2H,) 7.15 (dd, J=8.97, 2.40 Hz, 1 H), 6.80 (d, J=3.79 Hz, 1 H), 3.91 (s, 4 H), 2.52 (s, 3 H).
