Procedure
To a mixture of cyanuric chloride (50 g, 271 mM), acetone (200 ml) and ice (300 g) was added, over ten minutes, a mixture of indoline (32 ml, 286 mM) and 2.5N hydrochloric acid (120 ml). To this stirred mixture was added, over one hour, a solution of sodium secondary phosphate which had been prepared by neutralising 2.5N sodium hydroxide (250 ml) with orthophosphoric acid to PH 7 to 7.5. The mixture was then stirred for one hour, filtered and the resultant solid was washed with water and dried at 80° C. There was thus obtained 2,4-dichloro-6-indolin-1-yl-1,3,5-triazine (72.4 g, 87% yield), a portion of which was recrystallised from toluene, mp 254°-256° C. NMR: DMSOd6 : 3.15-3.3 (2H, t, CH2CH2 --N), 4.05-4.3 (2H, complex, CH2CH2N--) (rotamers), 7.0-7.4 (3H, complex, aromatic), 8.15-8.4 (1H, complex, aromatic).
