Reaction Steps

A mixture of (2S)—N,N-dimethyl-2-[(4-oxo-3,4-dihydroquinazolin-5-yl)oxy]propanamide (200 mg, 0.77 mmol), triphenylphosphine (603 mg, 2.3 mmol) and carbon tetrachloride (2.2 ml, 23 mmol) in 1,2-dichloroethane (5 ml) was stirred at 45° C. for 2 hours. 1-(Pyridin-2-ylmethyl)-1H-indazol-5-amine (179 mg, 0.8 mmol) was added and the solvent was evaporated under vacuum. Acetonitrile (5 ml) was added. The mixture was stirred at 75° C. for 2 hours. After cooling, 6N methanolic ammonia (3 ml) was added. The solvents were evaporated under vacuum. The residue was purified by chromatography on silica gel (eluant: 3% to 5% methanol in DCM) to give the title compound as a white foam (208 mg, 58%); NMR Spectrum (CDCl3) 1.72 (d, 3H), 3.06 (s, 3H), 3.14 (s, 3H), 5.43 (q, 1H), 5.75 (s, 2H), 6.81 (m, 2H), 7.17 (m, 1H), 7.41 (d, 1H), 7.48 (d, 1H), 7.62-7.53 (m, 2H), 7.81 (dd, 1H), 8.10 (s, 1H), 8.44 (d, 1H), 8.58 (d, 1H), 8.62 (s, 1H); Mass spectrum 468.
