Reaction Steps

0.45 g of 4-chloro 6-methyl quinazolone and 0.405 g, of m-trifluoromethylaniline in 20 ml ethanol were refluxed 1 hour. Treatment with aqueous Na2CO3 and extraction with CH2Cl2 gave 0.2 g of P15 as a white solid, mp-215° C., as the free base. NMR CDCl3 δ 8.78 (1H, S), 8.06 (2H, m), 7.86 (1H, d, J=7.6 Hz), 7.65 (2H, m), 7.54 (1H, t, J=8.0 Hz), 7.42 (1H, m), 2.58 (3H, S).
