Chlorotris(triphenylphosphine)rhodium(I) (40 mg) was added to a solution of 4-[(5-{(1R)-2-[allyl(methyl)amino]-1-methylethoxy}quinazolin-4-yl)amino]-2-chlorophenol (841 mg) in acetonitrile/water (5:1, 4 ml), and the mixture heated to 130° C. for 10 minutes by microwave irradiation. The cooled mixture was subjected to ion exchange chromatography and product eluted with methanol/2M ammonia yielding 2-chloro-4-({5-[(1R)-1-methyl-2-(methylamino)ethoxy]quinazolin-4-yl}amino)phenol as a brown solid (776 mg, 100%); NMR spectrum (DMSO-d6) 1.40 (d, 3H), 2.33 (s, 3H), 2.87 (m, 2H), 3.29 (1H obscured by water), 4.88 (m, 1H), 6.97 (d, 1H), 7.14 (d, 1H), 7.28 (d, 1H), 7.55 (dd, 1H), 7.68 (t, 1H), 7.95 (d, 1H), 8.45 (s, 1H), 10.51 (bs, 1H); Mass spectrum MH+ 359.
