A compound of the formula (I):
wherein
W, is a hydrogen atom or a
group wherein Y is a C1-6 alkylene group or a C1-6 alkylene group having a C1-6 alkyl group substituent; and R, and R2 each independently is a hydrogen atom or a C1-6 alkyl group and R,, R2 and the adjacent nitrogen atom may form a C4-6 heterocyclic ring or a C4-6 heterocyclic ring containing an additional nitrogen atom and the C4-6 heterocyclic rings may have at least one C1-6 alkyl group, hydroxyl group or halogen atom;
W2 is a hydrogen atom or a
group wherein Z is a C1-6 alkylene group or a C1-6 alkylene group having a C1-6 alkyl group substituent; and R3 and R4 each independently is a hydrogen atom or a C1-6 alkyl group and R3, R4 and the adjacent nitrogen atom may form a C4-6 hetercyclic ring or a C4-6 heterocyclic ring containing an additional nitrogen atom and the C4-6 heterocyclic rings may have at least one C1-6 alkyl group, hydroxyl group or halogen atom;
when W, is a hydrogen atom, W2 is the
group; and
when W2 is a hydrogen atom, W, is the
group; and the pharmaceutically acceptable acid addition salt thereof.
