In the above article, published in issue 49(3) of the Synthetic Communications, Table 3 appeared with minor error. Substituent R² for compounds 5b and 5c should be corrected as “C₄H₉” and “C₂H₅” instead of “C₂H₅” and “C₄H₉” respectively. This error does not influence any other parts of the paper.

The corrected version of Table 3 appears below:

Table 3. Synthesis of pyrimidine analogs of Tacrine.

Product	R^1	R^2	Yield^a(%)	m.p. (°C)
5a	4-ClC6H4	C2H5	47	219–220
5b	4-ClC6H4	C4H9	51	232–234
5c	4-(MeO)C6H4	C2H5	43	190–192
5d	4-(MeO)C6H4	C4H9	40	224–226
