Procedimiento

In a procedure analogous to that described in Example 1, 1-methylnaphthalene (142 g, 1 mol) was condensed with formaldehyde (170 mL, 2.25 mol) in acetic acid solvent (175 mL) using sulfuric acid (25 mL) catalysis. After reacting for 24 hours 2-naphthol (143 g, 1 mol) was added over 7 minutes. The reaction mass was heated under reflux an additional 5 hours and worked up as in Example 1. The results are shown in Table A.
