The procedure (including reaction and treatment) of Example 2 was repeated, except that 5-benzyloxy-α,α,α′,α′-tetramethyl-1,3-benzenedimethanol was replaced by 5benzyloxy-α,α,α′,α′-tetrapropyl-1,3-benzenedimethanol, to thereby yield the above-described target as a pale yellow oil. IR(film)cm−1: 3348, 2957, 2929, 1617, 1595, 1502. 1H-NMR(CDCl3)δ: 0.83(12H,t,J=7.3 Hz), 1.08-1.22(8H,m), 1.41-1.60(8H,m), 2.42(2H,t,J=9.4,5.7 Hz), 4.59(1H,br.s), 6.42(2H,s), 6.48(1H,s).
