Pyrazinedicarbonitrile (169) gave 3-methoxy-2-pyrazinecarbonitrile (168) (MeOH, EtsN, Me2NCH0, reflux, 16 h 30%) or dimethyl 2,3-pyrazinedicar-boximidate (170) (MeOH, MeONa, 20C. 18 h 64%). ... [Pg.218]

The same substrate (91) and triethyl orthoacetate, however, gave a separable mixture of 5-ethoxy-3-methoxy-5-methyl-6-phenyl-4,5-dihydro-2-pyrazine-carbonitrile (93) and 3-methoxy-5-methyl-6-phenyl-2-pyrazinecarbonitrile (94) (likewise 35 and 43%, respectively) the dihydro product (93) gave its aromatic counterpart (94) quantitatively by loss of ethanol on treatment with pyridine or triethylamine.857... [Pg.16]
